Space-Based Monitoring activities
Environment Canada lead: Mike Manore
1. 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– ownership for national SAR wind system
▪ future missions– influence future missions to meet EC requirements – Canada (CSA), International– E.G. CSA PCW mission– Chinook mission – no longer in the plan

Canadian observations - MTDCF
• Two major areas of development underway for MTDCF (leads are Tony Colavecchia and Yves Pelletier)
• Radiosonde data: Using Vaisala software at each site to generate both alphanumeric and BUFR bulletins (template with 4D trajectory). BUFR data from 2 sites received and validated at CMC. Awaiting telecoms upgrade for full network deployment
• Surface data: Will have centralized processing (DMF initiative) using raw data formats from stations to encode in BUFR using template 3 07 080 plus a national template extension. Data from SYNOP, METAR and SA will be in BUFR. Test data to be available at CMC during Summer 2011.
• Will need a transition period when data in both BUFR and alpha. codes would be available. Some data processing adaptation to do (both NWP and forecast applications) and need to have some data to do so!
• Have started to process international data fro NWP and DMF.
NAEDEX-23 and APSDEU-11, Boulder – May 02-06, 2011Meteorological Service of Canada Status Report
Canadian observations
• Canadian radiosonde data – still alternating between Loran sondes (no wind) and GPS sondes, roughly ½ network each. To be completed by end of Summer. Issue related to large stock of Loran sondes. Additional cost to operate 100% GPS is $1M.
• Canadian radar data - available at CMC, NRP (National Radar Processor) is operational, full volume scans available. Available to NOAA on CMC datamart but not yet in BUFR. No QPE product yet. Issue of data exchange format.
• Some research wind profilers in Southern Ontario and Quebec: operated by University and private company, data now available to CMC from 8 sites and should be inserted on GTS once validated, in BUFR code (OPERA software): headers to be communicated as soon as available. Another 2 sites in 2011, but significant issues with operating funds. Data quality issues have been identified and is slowing down progress.
• 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 as part of MTDCF.
• Co-operative network in Quebec (Province, Hydro-Quebec, etc), received at CMC, also redistribution restrictions…data now in BUFR.
• Some soil TT data now available, eventually in BUFR. Alphanumeric format could be made available.
• Ozone soundings on GTS (KULA01 CWAO) and total column ozone.
NAEDEX-23 and APSDEU-11, Boulder – May 02-06, 2011Meteorological Service of Canada Status Report
• “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 and NOAA : surface elevations are not available or wrong. Data should be inserted by each individual country and not by CMC.
• SAR-Winds: Demonstration application generates marine sfc winds from SAR and ASAR imagery (Radarsat and Envisat). Fairly high resolution over small areas, wind direction information obtained from NWP model (LAM or REG) or from cross-polarization if available. One-year transition before full operational transition.
• Canadian AMDAR – very little change to operations:• AC Jazz: data from 25 CRJ on GTS, all on GTS. Data received from 4 DHC-8
only, but retained due to ongoing problems with data quality of DHC-8.• Also obtaining data from 2 NavCanada CRJ’s, data quality is good and
transmitted on GTS. Often in remote areas and low levels.• No progress with other airlines.• MSC-ADAS system and software is used for data reception and processing,
in-house Linux based system. Fully redundant.• Monitoring of data is on-going and showing importance of good monitoring
before distribution of data.

Other data issues
• SSM/I F15 – Still received and used for operational ice analysis• Future plans for Scatterometer? Availability of OceanSat?• Access to SMOS data ? Data volume (10 GB/day is problematic for
NRT NWP (CaLDAS). Need a lower volume NRT product.• Would like to access direct broadcast FY-3a. Agreement signed
with CMA, but still need technical information to adapt AHRPT receivers and processing software (any info. would be useful). Interested in accessing Global sounder data if available?
• Collection of global ADS-Met data. Recent increase over North Atlantic appears mostly uncoordinated? What about expansion of ADS in other areas?
• GeoNetcast system for Americas – with similar content as Eumetcast Ku band?
• Access to other GPS-RO instruments if possible.• Issue with change in COSMIC GPS-RO in Oct 2009

Changes to CMC NWP System since last meeting
March 2011 – CIS 3D-Var NOAM Ice Analysis• Explosion in availability of SAR data in next 5 years, and rapid evolution in
quantity of ice products to generate• Need to automate some labour intensive tasks at CIS• Goal is to produce automated analyses of sea-ice conditions for
operational needs of MSC:• enhanced ability of CIS to deliver operational sea-ice products over larger
area than currently possible
• improved NWP by supplying better sea-ice analyses for initializing coupled ice-ocean-atmosphere forecasts in the Arctic.
• Using NWP-like data assimilation set-up, 5-km NOAM grid• SSM/IS and AMSR-E using Nasa-Team-2 algorithmSSM/IS and AMSR-E using Nasa-Team-2 algorithm• CIS RadarSat image analysis and daily ice chart (manual analyses)CIS RadarSat image analysis and daily ice chart (manual analyses)• CIS lake analysis (manual analysis)CIS lake analysis (manual analysis)• First automated product at CIS to be Davis Strait Ice Edge• Global configuration (10-km) in preparation for operational NWP at CMC• Future: Assimilation of scatterometer, visible-infrared, SAR/ASAR and ice
