Organizational Structure
‘Space-Based Monitoring’ - Environment Canada lead: Mike Manore1. understanding satellite data requirements
▪ Environment Canada wide▪ meteorological, climate, ice, marine oil spill, wildlife habitat, etc,….
2. ensuring data access & exchange▪ coordination/arrangements with satellite operators and other users
– gov’t-to-gov’t, gov’t-to-agency, commercial– MoU with NOAA, Agreement with Eumetsat…– all appropriate missions and sensors
▪ operation of EC satellite data reception and processing systems– within Gov’t of Canada ‘Shared Federal Infrastructure’– EC leadership for operational meteorological missions– operate as a national network: GOES- Alfheim; HRPT - Bradley
▪ future missions– influence future missions to meet EC requirements – Canada (CSA), International– E.g. CSA PCW mission

CSA PCW Mission
• Cooperation CSA, DND, EC• Concept of 2 satellites in HEO (Molniya 12-hr
orbit)• ABI-like imager, 2015 timeframe• Proto-operational, North Polar areas only (Nof60)
(2 other sat. needed for South Polar areas)• Phase 0 just completed• Phase A kick-off next week, opportunities for
cooperation to be examined• Mission funding not yet secured• EC: Louis Garand, Mike Manore, Gilles Verner

Canada-EUMETSAT Cooperation Agreement
• Signed Fall 2007
• 8 areas of cooperation– science and product development
▪ participation in SAFs, visiting scientists
– optimize data acquisition and exchange of satellite data and products▪ specific agreements –e.g., EARS
– define requirements and opportunities to improve high-latitude observations
– explore options for Canada to contribute to EUMETSAT mission instruments▪ build on CSA associate membership in ESA
– share training experience and materials
– cooperation in GEO, including projects in developing countries▪ GEONETCast
– exchange views on matters of satellites and satellite meteorology
– explore possibilities for longer term cooperation
NAEDEX-21 Asheville, NC. – September 17-19, 2008Meteorological Service of Canada Status Report
Computers and Telecoms
• Final upgrade to IBM: 2 clusters, upgrade is underway:– current is OPS: 40 nodes, and R&D: 60 nodes– to reach OPS/DEV: 80/120 nodes by Dec08, and– to reach 80/180 nodes by June 09– Total of 4512 P5+ processors (9024 virtual) by mid 2009
• New procurement for 2010-11• Upgrade to SGI-FE’s: 2 x capacity, replacement with Linux
clusters underway• CFS: 2 PB tape capacity• Links to NOAA-TOC (GTS), UKMetO (Sat data + GTS back-
up), EUMETSAT (EARS)• Link to NOAA-NESDIS soon (may be done by now)• Internet still used for much satellite data• EumetCast / GeoNetCast being considered

Canadian AMDAR coverage
NAEDEX-21 Asheville, NC. – September 17-19, 2008Meteorological Service of Canada Status Report
Canadian AMDAR - Status
• AC Jazz: 46 CRJ and 42 DHC-8 on GTS, 2 CRJ and 14 DHC-8 retained due to problems with data quality. More CRJ to be added. CRJ data very good. DHC-8 may be removed.
• Still issues with DHC-8 TT data, although improved. Problem is related to data averaging aspects in avionics. Not corrected.
• No progress with AMS and First Air. TAMDAR approach does not seem viable for these aircraft.
• Still trying to obtain data from NavCanada CRJ’s (2), hopefully to be this fall. Some data samples just obtained.
• Negotiations on-going with WestJet, slow progress.• MSC-ADAS has replaced former C-ADAS software, in-house
Linux based system.• Monitoring of data is on-going and showing importance of good
monitoring before distribution of data.
NAEDEX-21 Asheville, NC. – September 17-19, 2008Meteorological Service of Canada Status Report
TT data quality – JAZZ CRJ and DHC-8
For DHC-8 Aircraft, significant difference in bias between ascent /
descent data.
Related to smoothing algorithm in avionics.
CRJ Aircraft data are good.

Other Canadian observations
• “Synoptic” observations from CTBTO network, using SYNOP MOBIL code, header: SNCN19 CWAO. Observations every 10-min, 10 stations for now but should increase, received at CMC by e-mail: data problems as reported by MetOffice : surface elevations not available or wrong.
• Canadian radar data - now available centrally at CMC, NRP (National Radar Processor) operational, full volume scans available. Provided to NOAA.
• Forestry and Road weather stations in British Columbia - data received at CMC, in old SA format. Data redistribution restrictions currently apply…should eventually be available in BUFR.
• Co-operative network in Quebec (Province, Hydro-Quebec, etc), received at CMC, also redistribution restrictions…problems with BUFR data.
• Some research wind profilers in Southern Ontario and Quebec: operated by Universities, data now available to CMC and should be inserted on GTS in the near future, in BUFR code: headers to be communicated as soon as available.
• Some soil TT data now available, eventually in BUFR.• New equipment for radiosondes. Should improve wind quality, also includes provision
for 4D data in BUFR. Data available at stations but not yet on GTS.• Ozone soundings on GTS (KULA01 CWAO) and total column ozone.• Major data management project in MSC, should lead to all data available in BUFR.• Potential development of surface GPS Network. Lead: Godelieve Deblonde.• Surface Weather stations for 2010 Olympics (Whistler) already on GTS.

Some data issues
• SSM/I data : any chance to get F15 back, status of F14?
• SSM/I data quality issues – some stray scans and orbit identification and/or positioning/labelling
• SSM/IS – status to be discussed at this meeting, F17-18
• « Slower » access to Metop data
• Access to some data on GTS has been problematic to CMC: IASI (300 ch subset) due to link saturation, dropsondes over Western Pacific (obtained from MetO),
• AMSU – timeliness of N15, N16 (not primary)
• Need for a Eumetcast-Europe-like system for Americas – GeoNetcast with similar content as Eumetcast?

Changes to EPS implemented July 10, 2007
a) New physics / New dynamics / Horizontal resolution
• 20 GEM members (SEF not used in the new EPS)
• Horizontal resolution: 0.9°
• Model lid: 10 hPa
• Forecasts up to 16 days
• Inclusion of two stochastic components in the physics
• Multi-parameterization approach...
• ENKF – True 4D with FGAT like innovations, 0.9°
• Harmonization with NCEP for NAEFS
NAEDEX-21 Asheville, NC. – September 17-19, 2008Meteorological Service of Canada Status Report
New Set-up for EPS
b) Stochastic physical tendency perturbations
• All physical tendencies on horizontal winds, temperature, and humidity of each member are multiplied by a random function:– Defined in the range [0.5 , 1.5]– With a decorrelation time scale of 3 hours– And a decorrelation length scale of ~1700 km
NAEDEX-21 Asheville, NC. – September 17-19, 2008Meteorological Service of Canada Status Report
New Set-up for EPS
c) Stochastic kinetic energy backscatter algorithm
• Numerical models are over-dissipative near the truncation limit
• This likely inhibits upscale energy transfer that can affect the large scale flow
• It is thought that this phenomenon can be a cause of under-dispersion in EPSs
• Parameterization: Inject energy near the truncation limit to compensate for the over-dissipation
