PLAN:


WIGOS- DP

Demonstration projects conducted by NMHSs are considered as an essential component in WIGOS implementation:

• Helps WMO Members to more fully understand WIGOS concept and keeping them current on its practical development. • Feedback and lessons learnt from these NMHSs will be extremely beneficial in understanding others’ expectations of WIGOS/WIS concept and implementation.

Introduction:


Moroccan WIGOS Demonstration project

•To Improve the quality of climatic and meteorological observed data in the perspective of a better integration of the climate in the National sustainable development,• To ensure that the national metrological measurements respond to WMO standards.

• What is the quality of the measurements of the National Meteorological Surface Observing Network, and

• In which conditions they are made???? 4

WIGOS Priorities: • To ensure the quality of the observation to meet climate en environmental

requirements, and• Metadata and Homogeneity for long term stability..


WIGOS Demonstration Project in Morocco consists on standardization and traceability project that include: 1. Strengthening material capacities and human knowledge of the Moroccan Regional Instrumentation Center (RIC) for AR-I and improving its technical procedures to allow it to accomplish its task of calibration in link to recognized Metrological International chain ,

2. Establishment of Metadata catalogues of the whole synoptic, marine, aeronautic and automatic weather stations constituting the Moroccan Meteorological Surface observing Network.

To calibrate and to achieve traceability of the national

meteorological observing Surface Network

IMPLEMENTATION PLAN:Project 1:

As suggested by CIMO, the four following domains were selected as areas of enhancement : a) Setting up of laboratories and purchase of standardization devices; b) Quality Insurance and control;

c) Training;

d) Assessment of the RIC.

Project 2: • Seeing the rapid expansion of cities, more and more synoptic station had seen their sitting environment modified and in some cases not fulfilling to standards. • Information related to calibration, renewing instruments and sensor exposure are not archived. By this project, it’s expected to produce documents describing instrument metadata, as well as, equipment life-cycle:

o Instrument/network sitting, o Calibration, renewing and maintenance.

8

IMPLEMENTATION PLAN:


Preliminary actions: • Upgrade of existing laboratory equipments: repairing existing equipments and connecting sensors and standards used with the different equipments to a computer in order to optimize data collection).

• Construction of a new building to house the laboratory

9


Achievement Progress:

For the strengthening of RIC capabilities, three stages were defined: 1.Acquisition of standards and calibrating equipments to calibrate instruments measuring atmospheric pressure,

2. Acquisition of standards and calibrating equipments to calibrate instruments measuring temperature and humidity,

3. Acquisition of calibrating equipments for rain gages.

Training Activities:

19

• 2008: RIC Staff received training on metrology of pressure and on installing and handling the new pressure calibrating system,

•December 2009: NMS of Morocco hold the French session of the WMO course on metrology for the AR-I French speaking countries,

• May 2010: The technical staff of the calibrating laboratory follows the training in matter of metrology organized by the African Commission of Metrology (CAFMET).


Quality Insurance:•NMS of Morocco started, in 2008, a quality circles for support processes like maintenance and calibration.

• Standards Intercomparison with Meteo-France calibrating Laboratory (RIC for AR VI) was also achieved in July 2010,

• During the meeting of the CIMO ET on RICs held in Casablanca, the participants have engaged an assessment test of the RIC of Morocco with regards to the ISO 17025 requirements and RIC TOR using the new template evaluating Scheme developed by the ET.

• NMS of Morocco launched the project of certification of the RIC with regards to the ISO 17025 standard. (the certification project is expected to be achieved by the end of 2011)

Experiences gained and problems encountered:

The NMS of Morocco and especially its calibrating laboratory considers that experiences have been acquired in the following areas:

• Making benefit from WIGOS values and taking part, while being satisfied, to its implementation, • Definition of needs and establishment of technical specifications of each materiel to be acquired,• Management of the acquisition process (budget, acquisition project achievement…),• Acquiring knowledge in matter of Metrology and processes related to the calibration of meteorological instruments,• Implementing quality control process.


25


• A real difficulty was encountered during the development of calibrating software. In fact, there was a need of help of technical expert for providing the way to calculate and determine metrological parameters (uncertainty, hysteresis, repeatability…).

To overcome this problem, a technical assistance was provided by RIC of AR -VI.

In this context, WIGOS should encourage cooperation between developing and developed countries in matter of interest.

This cooperation should lead to a real knowledge transfer.


26


• Difficulties were also encountered when bringing barometers from station to laboratory (need of replacement).

RIC acquired, to resolve this problem, necessary digital barometers with LCD screen to replace mercury barometers not fulfilling WMO standards. (18 digital barometers were acquired in 2009).

WIGOS should emphasize the practical application of its terms of reference.

The implementation of the concept of WIGOS at different levels (observation, coding and transmission, modeling, dissemination ...) will generate some friction that may be exceeded by the definition of clear and comprehensible procedures and deliverables.


27

Conclusions:• NMS of Morocco took into charge the actions mentioned above and the progress of the project is consistent with the timetable presented to the EC WG on WIGOS.

• The NMS of Morocco has just completed a large part of the project with regards to the IP and more efforts are now oriented to develop, to practice and to assess technical procedures for calibrating processes according to ISO 17025 standards.

• During the accreditation process, a certified consultant will assist the RIC staff. However, Experience of developed and certified RICs will be a precisous aid seeing the fact that, in general, RICs uses to calibrate similar instruments working in same ranges and responding to the same WMO tolerances.
