DISCUSSION CHAIRED BY DR R. SORANI (VICE CHAIRMAN) COST-73, ITALIAN MET SERVICE

Issues raised at the Seminar as perceived by C.G. Collier (Chairman COST-73, UK Met. Office) presented as a basis for discussion:

1. Should European radar development be seen as the separate development of disparate programmes, or should we view the future as an integrated programme within which national variety can flourish?

2. Do the benefits of international radar co-operation and data exchanges justify allocation of appropriate resources to the necessary co-ordination task?

3. How best can radar technological transfer be accomplished throughout Europe? Should the radar community in Europe hold a conference every 2-4 years (say), and if so who should organise it?

4. Will the cost to users of radar data inhibit both the use and development of radar networks in Europe?

5. How do we ensure that radar manufacturers in Europe benefit from R&D? Do meteorologists need to worry, or should market forces decide future developments?

Dr R. Sorani (Vice Chairman COST-73j Italian Meteorological Service):

It would be instructive to begin by considering how the issues raised by Chris Collier [above] could be considered in the near future. We do not know the point of view of the World Meteorological Organisation, but we have here with us Dr Jim Rasmussen (WHO), and I would like to invite him to give his reactions to the presentations and discussions over the last 3 days.

Dr J. Rasmussen (Director World Weather Watch Department, WMO):

Thank you very much. I know that time is short, so I shall reduce this pad of paper that contains my comments to a few signicant points. Chris has written down his view of issues - those are his views, but I thought it would be helpful to comment on some of them because the questions are quite important.

The World Weather Watch (WWW) is seen to operate on quite a different scale from the scales associated with the radar networks which have been discussed this week, and it has been personally refreshing to deal with people who are actually acquiring, processing and displaying the data in creative ways and making forecasts estimating the quantity of precipitation. However, the WWW is simply an aggregation of observations and data exchange programmes - one of which we have discussed here. I have enjoyed this "real world atmosphere" very much. We have just finished the WHO Congress, it takes place every 4 years, and there is a comprehensive level of discussion on all aspects of meteorology, as you might imagine. Also it is very refreshing to come back to the real world, and instead of talking about organisational matters, such as what commission is going to do this and what commission is going to do that, and actually talk and listen to people who are doing basic things in a particular field, so I personally have appreciated this break, especially since it has followed the WHO Congress so closely.

One point that does concern me is the lack of heated discussions during the Seminar, everybody seemed to agree with everything that was reported here.

There were very few sharp exchanges. Being an American I was involved with the development of the NEXRAD system shown on the top-line of Chris' chart (transparency shown in Collier's presentation, see paper in this Volume) where he was summarising the world radar networking scene; I was involved in the planning exercises on what the NEXRAD system should be. There were very heated and emotional discussions with the research community on whether to have such things as dual polarisation, network density and archive strategies, and I wondered when similar arguments were going to occur at this Seminar. By and large there were not any except for the little bit of such debate today. There are big issues between the operational side and the research side concerned usually with 'How are we going to pay for all this good stuff?' Unfortunately somebody has to draw that line which often separates that part of the technology that would be nice to have, from that which cannot be accommodated on cost grounds or feasibility at the time that the decision has to be made. These kinds of struggles expose issues and force the programme managers and scientists to seek the best possible solution with the resources available. I am happy to see Europe facing these problems in a cooperative way.

The radar - if I might make another comment - is just one of a whole variety of tools that a meteorologist uses. I realise that this was a radar conference, so one is not going to talk about the rest of the meteorological story, but I want to emphasise that this is just one of the exciting new and developing observing systems available to meteorologists. Other systems, of course, include the standard meteorological networks, and the exciting things happening in the automatic weather station arena as well as wind profilers, measurement systems deployed over the ocean, automatic airborne systems and improvements in satellite technology. For example every wide-bodied aircraft that takes off and lands ought to produce a sounding for us using data from its avionics system. If we could only achieve this, we would reach about 50% of the WWW data requirement over regions of the world where there is very little data. Regions such as Africa, for example. Each one of these aircraft has an internal navigation system capable of providing a wind profile of a quality equal to that of a rawinsonde. We just simply have to move on and take advantage of the opportunities that exist.

with regard to radars, again looking from the WWW point of view, I would love to see high quality winds from Doppler VAD systems flowing on the WWW communication circuits. There are around 50 Doppler systems soon to be established in Europe. I would think a good objective would be to get those radar-based data that are really required for all meteorological analayses into the operational data processing system and hence, into the numerical forecast models.

The network in Europe also demonstrates, in a very visual way, the possibilities that exist for international co-operation. Radar composites are very visual things, and if we can start showing European composites of radar images frequently in the weather programmes on television, people start seeing what is happening in other places and can visualise the weather moving across the map. It illustrates the need for international cooperation in meteorology and for that matter all environmental matters.

On a couple of occasions at this seminar an issue was raised that I would label as "truth in packaging", namely that it really does not matter what the product is as long as it looks nice people will buy it. I have had experience of this when dealing with the hurricane problem in the United States. The fact is the hurricane warning is put out in a product that looks super, combining satellite, aircraft and radar observations, and the general perception of people is that we can forecast tropical cyclones very accurately because the visual impact that comes over on the television is so good. People really think that

309

meteorologists know What is going to happen in detail, and it is very difficult to tell them that there is a high error porential in the forecast. The perception of the public is that we are much better at forecasting some things than we really are. I think that, as meteorologists, we have to continue to try to define a "truth in packaging" policy, and work on it, so that in the end our communities accept this approach. In the long-run the public is best served by a wise use of forecast information.

Mr Chairman, I could go on, I have quite a long list here, but I think those are the main points I would like to highlight.

Dr R. Sorani:

Thank you very much. I know it is possible to go on discussing these matters, but what is important is that we realise and appreciate from your words that WHO will support our work in the future as in the past. In less than three weeks from now a WHO working group will meet in Paris during the Radar Conference. This working group was established by the WHO Commission for Instruments and Methods of Observation (ClMO). In addition the European Community COST Programme has established an ad hoc COST-Technical Committee for Meteorology. This Working Group has some particular tasks, and I would like to invite Fritz Neuwirth (Austria), Who is here representing the chairman of the working group, Mr McWilliams (Ireland), to give some information and make any observations as vice-chairman, of this committee.

Dr F. Neuwirth (Vice Chairman COST Technical Committee for Meteorology, Austria)

Thank you Mr Chairman. First of all, I really have to apologise for Mr McWilliams, Who is unfortunately unable to attend this meeting, because at the same time he has to be at a Eumetsat Council meeting. The advantage of Mr McWilliams' attendance would be that he would be able to speak in better English than I can, but I shall try my best.

The Technical Ad Hoc Committee for Meteorology of COST was established last year by the COST Senior Officials committee which is the executive committee of COST. The terms of reference of this ad hoc meteorological committee are, in general terms, to identify and encourage joint research and development projects likely to contribute to progress and understanding in the field of meteorology, based upon existing European structures. In carrying out their work this committee has also made proposals for joint actions under the aegis of COST in Europe after considering whether they are worthwhile. We have begun by making an inventory of ongoing meteorological research in the different participating countries. Based upon the results of a questionnaire a small working group is making a draft inventory of meteorological research Which, hopefully, will be available in autumn of this year. We also have to submit, at the end of this year, proposals to the senior officials committee for new actions in COST. At our last meeting, the committee agreed that following the recommendation made by COST-73, operational aspects of international radar data exchange should be referred to a committee established by the western Directors of European Meteorological Services. In addition, as mentioned by Mr Collier, the COST Technical Committee agreed that it would recommend to the senior officials committee a new COST action based upon the proposal drafted by the COST-73 Management Committee. Hence I believe that, from the point of view of the COST Technical Committee for Meteorology, everything is in line to proceed with a new COST action.

310

I think this is more or less all that I have to say regarding the work of the COST Technical Committee. However, I would like to make a few further comments as an Austrian meteorologist. We in Austria are really happy about the new situation in Eastern Europe, which opens up new possibilities for co-operation. Also we welcome the news that Poland, Hungary and Czechoslovakia will become official members of the COST family during the COST Forum at the end of November this year in Vienna. Since last year the Austrian Met Service has established, at the level of the Directors of Meteorological Services in this region, an informal liaison committee, and we have had two of these conferences so far; at the first the Directors agreed to try at least to establish radar networks in these countries, and work began on a technical feasibility study which would be carried out by Dr Randeu (University of Graz). Next week in Graz a small seminar of experts from the different countries, Poland, Hungary, Czechoslavakia, Slovenia and Croatia and of course, Austria, will try to prepare an action plan for the next steps towards realising a Central European radar network. I personally have a dream that in our region we will have a successful co-operation similar to that the COST countries have established so well.

Dr R. Sorani:

Thank you very much. I can only add a few words as a postscript. I know that on 14-15 June the COST Senior Officials will meet, and the proposal for the new COST project will be discussed for the first time. Let us hope that the senior Officials decide to accept our proposal.

Concerning the enlargement of co-operation to the eastern European countries, we note the new initiatives being undertaken. Yesterday the first meeting of European Meteorological experts met in Budapest in the framework of "Pentagonale". Many projects concerning meteorology were presented and discussed. Tomorrow we have another meeting on similar matters to be chaired by Dr Tokdemir (Ministry of University and Research and COST Senior Official of the Republic of Italy), and so it seems that this month (June) will be known in the Chinese calendar as the month of meteorology as well as the month of romantic and poetic phenomena. Before we close this seminar let me thank you all for your participation. Some of you will be in Graz, and we will continue our work in Graz. Others will go back to their own countries, and I wish everyone a pleasant trip back home. Before we close formally this seminar I would like to thank our interpreters for their help during the last few days, and I would like to thank the local organisers for their efficient organisation. Everything was perfect in my view. I do not want to close formally this seminar just yet, because I want Chris Collier, as Chairman of COST-73, to act as chairman of an open general discussion.

C.G. Collier (Chairman COST-73, UK Met Office):

We have a little time left, and before we finally close I would invite participants to comment on any of those questions (listed above) raising particular issues. I have tried to be a little controversial, in particular with questions 4 and 5, and I wondered if I could invite anybody who would like to comment to do so on those questions first.

If we look at question 4, for example, will the cost to users of radar data inhibit both the use and development of radar networks in Europe? This is a point, I think, that has been touched upon in the last few days. We have heard

311

from the marketing people that they wish to market the data in a very agressive way - will this have a detrimental effect on the development of operational systems, or should we let them take their course?

And the fifth question is the same kind of thing - how do we ensure that radar manufacturers in Europe benefit from research and development which is taking place? Should we, as scientists and meteorologists, worry, should we just let market forces take their course, or should we actually get together with radar manufacturers and attempt to influence what they do? Any takers?

R. Thebault (Jersey Met Office):

As a practising forecaster and someone who runs a weather centre, I think that, provided the cost of running a weather radar remains at about the same level as it is now in the future, then weather radar and more especially, a weather radar network is good value. It is vital to accurate forecasting in the short term. It gives our forecasts the sort of precision that enables our customers to have confidence in them and this is quite important.

Looking forward to where we go from here, there is no doubt in my mind that COST-73 has been the driving force which has enabled a European Weather Radar Network to come about and it has certainly provided the momentum for this to happen. I think it would be unfortunate if this momentum was now lost as there is still much work to be done in order to complete this network and, although I do not wish in any way to take away resources from other areas of work, I wonder if in looking at the follow on project we should not include something, a statement shall we say, calling for work towards a European Weather Radar Network to meet the needs of the 21st century. Thank you.

C.G. Collier:

I would agree with you. What has happened, or what seems to have happened, is that there is now a partition between the operational development of radar and the research development of radar. The operational aspects will be addressed, by the Toulouse working group established by the Directors of Western European Met Services, and the more research aspects will be developed under the COST umbrella. Now, whether that is the right way forward, or whether there is a danger that some matters may fall between the two areas if we are not careful, is a real concern that you have highlighted, and I am not sure what the solution is. I think we just have to hope that people involved in those two groups can ensure that nothing is missed. I am encouraged, however, that positive action is being taken to ensure that the activites of COST-73 are continued.

Mrs V. Ballentine (UK Met Office):

Thank you, Chris. It has been mentioned that marketing ,and here I think the word is being used in the sense of 'selling', might be detrimental to weather radar developments and the research that goes into it. Marketing is not selling. Marketing is ensuring that the end users, whether they are the forecasters, the researchers or the people in industry, get what they require. The underpinning point is that research and development goes hand in hand with marketing so that users will eventually get what they want and this applies both to internal and external users. You mentioned that there are going to be two groups of people, the fact that they could possibly go in two different directions, is very worrying to me, because you need that interaction between the researchers and the operational people. It is a most important task to make sure that the needs of the two committees are met in conjunction with each other, because, as Roger Thebault has said, it is the use of weather radar in

312

forecasting that gives us the extra quality, professionalism and accuracy in our forecasts which is required, not only in the short term, but also to progress to other services including climatology. You have really got to marry the two committees together.

Dr R. Sorani:

Yes, marketing is not selling. I would say it is not only selling. It is, of course, identifying future benefits, as you said, but it is also selling now in Europe. This particular aspect is worrying the Directors of Meteorological Services, and that is why they have set up the Toulouse working group. The terms of reference of this group include, of course, the consideration of future co-operation amongst European national services, but also aspects of commercialization of radar data. I agree with you that we should look to the development of benefits and to the end users, but we cannot exclude from consideration the commercial aspects likely to arise.

C.G. Collier:

Any other points that anybody wants to raise? Can I draw your attention to the first point on the list - should European radar development be seen as the separate development of disparate programmes or should we view the future as an integrated programme within which national variety can flourish? COST-73 has attempted to bring people together.

G.A. Clift (Consultant, ex-Chairman COST-72, UK):

Thank you, Chris. Several points I would like to make, but I will not waste eveyone's time with all of them. I well recall that one of the main aims of the COST Programme as a whole, was that work should be done by various countries, together. There would be less duplicated effort, and some chance of doing work jointly, to the benefit of countries who did not have either the scientific effort or the money to do work on their own. One thing I have detected in the last two and a half days, is that still some of the COST countries seem to be duplicating effort, which I think is rather a pity. It seems to me, no criticism of what you have been doing Chris, or your group, that there is perhaps not enough integration of effort throughout the COST countries even yet. How you stop people doing their own thing, I do not know. After all we know, that in anyone country, in the UK for example, there are different groups in different places doing the same sort of work. There is after all a finite limit to the skills and aptitudes of people anywhere in the world, and I feel that some more organisation on these matters could be achieved. That is my first point.

May I ask a question? I well remember in the corridors of the Met Office in Bracknell, UK, being told in about 1969 that we should not be wasting our time with weather radar, that satellites were going to do it all. Even more recently, in the last 2 or 3 years, I have been told the same sort of thing. Is there any belief that there is a limited life for radar systems and that satellites will take over?

313

C .G. Collier:

No, there is no belief whatsoever! Yes, an active radar device will fly on a satellite in 1996-97 as part of the TRMM (Tropical Rainfall Monitoring Mission) Project, but, for example, sampling is a significant problem, and that is just one of the reasons why it will not actually measure satisfactorily surface precipitation over short time periods and small space scales. What will be done in that experiment is to combine those data with a range of data from other satellite sensors, and also to use ground data, such as raingauge and radar data to make adjustments to the space-based measurements. So ground based radars can offer measurements which cannot be provided by satellites. Ground based radar and satellite systems are, in my opinion, quite complementary. They are not competing technologies and should not be seen as such.

G.A. Clift:

Thank you. That was my own belief but I felt it was worth ra1s1ng. The other thing I have to say is something entirely different. One thing we have not mentioned at all - I must nail my colours to the mast - I am involved with purchasing operational systems and installing and maintaining them. The subject of maintenance has not been discussed at all. I find also in countries I go to that I am constantly asked "Where can I send my forecasters so they can be trained in radar meteorology?" There is a great lack of training facilities in the area of radar meteorology. I know that people who are interested in hurricanes can go to Miami and get a useful training, but in many of the developing countries there seems to be little if any proper training in the interpretation of weather radar data. Even in some of those countries which have modern radars this is also true. What we are in danger of doing at the moment is giving the users more products than they really need, and they are not going to use half of them because they do not know how to. Finally, as radar systems become more reliable, paradoxically it becomes harder for technicians to remain conversant with them. It is very important to recognise this, and plan to ensure technical expertise remains available.

C.G. Collier:

I think that is absolutely right. Training is absolutely essential to much of what we are doing and that is why we started to address that subject within COST-73. It is really very fundamental and most important. There are many issues that we would like to discuss, and I am only sorry that we have run out of time. I personally would like to thank you all for supporting this seminar; I would like to thank our guests. I hope that you have found it instructive -certainly it has been stimulating for me, and, as usual, exciting. I go back to the UK refreshed from meetings like this. I would like to thank the interpreters for doing such a wonderful job, they have helped to make this meeting a success, and I wish you all a safe journey home.
