International Data Acquisition (1/2) • RTH-Washington • most of our GTS bulletins • GTS backup: UCAR-UNIDATA,NOAAPORT • RMDCN (MetOffice) • some GTS bulletins (EARS, AMV) • European BUFR (surface, raobs, bouoy) • PDA-NESDIS • Global AMSUA/AMSUB/MHS/HIRS - METOPA/B, NOAA15/18/19 (processed with AAPP) • AMSUA AQUA (BUFR) • SBUV - NOAA19 • SSMI - DMSP15 (TDRR) • SSMI/S - DMSP17/18 • GOME • AIRS - AQUA • AMSR2 - GCOM-W1 • Global ATMS/CrIS - NPP.NOAA20 • OMPS - NPP • PAMS – NPP
International Data Acquisition (2/2) • KNMI (ftp://ftp.knmi.nl/) • ASCAT METOP-1/2 • ScatSat (not yet) • UCAR-SUOMINET (https://www.suominet.ucar.edu/data/ncConusHourly/) • GPS Zenith Total Delay (in replacement for FSL) • CLS (ftp://ftpsedr.cls.fr/) • Buoy + argos insitu data • CMEMS (ftp://nrt.cmems-du.eu/) • Sea Level Anomalies from diverse satellite sources • NASA (ftp://podaac-ftp.jpl.nasa.gov/) • OMI/Aura OMTO3 (total column ozone) • AVHRR/VIIRS (Sea Surface TT)
Canadian data, Production and Dissemination • Data Management System • DMS is a platform for managing data and generating products • The initial focus was on MSC and third party point observation data. DMS provides these to a variety of internal and external clients and applications including: NinJo, NWP, the Archive, WMO • DMS has also getting involved in the management of raster data, satellite SAR winds, in future it will also get involved in radar data

Canadian data, Production and Dissemination • Radiosondes • 28 stations • 12 stations migrated to GRAW (from Vaisala) as of Nov 01st 2018 • TAC and BUFR bulletins issued at the stations • Geopotential height from pressure sensor • Presently mandatory and significant levels • High resolution observations to be tested soon
Canadian data, Production and Dissemination • SYNOP • 806 stations, 83 manned/723 automatic • Raw data is sent to the DMS in various formats • The DMS produces TAC and BUFR bulletins for all stations • Working on hourly reports early FY 2019
Canadian data, Production and Dissemination • SHIPS / moored buoys • 45 ships, 416 observations (Nov 1st 2018, 12Z ± 3h) • SHIPS • Raw message -> IMARSAT -> (Legacy system USA) -> DMS(FM-13) -> GTS • No BUFR • moored buoys • Raw message -> WBS (legacy system) -> FM-13 -> GTS • Raw message -> DMS -> FM-13 & BUFR, to be validated
Canadian data, Production and Dissemination • DRIFTING BUOYS • 737 BUFR observations, 84 TAC+BUFR (Nov 1st 2018) • BUFR bulletins produced by Scotia Weather Services Inc.
Canadian data, Production and Dissemination • METAR • 270 stations • 3 different formats (METAR,WinIDE,READAC) are sent to the DMS • The DMS generates METAR bulletins to be sent to the GTS
Canadian data, Production and Dissemination • AMDAR • Messages are provided to CMC by ARINC in ARINC-620 format • The MSCADAS system does QC on the data and generates BUFR bulletins to be sent on the GTS for the airplanes which are not blacklisted (old template) • The blacklist is updated monthly based on the QC control results
Canadian data, Production and Dissemination • C-AMDAR : Current Status • Present Canadian AMDAR program is and will continue to decline • Jazz is replacing it’s CRJ-200 with DHC-8/Q-400, which do not have capability of meeting AMDAR temperature accuracy requirements • As of Nov/2018 – 10 AC Jazz aircraft reporting Project Decommissioning Timelines
Canadian data, Production and Dissemination • C-AMDAR : Future • Early 2019 • Monitoring and QC will be done with two airlines, First Air and Canadian North • First Air Fleet • ATR 42-500 • ATR 42-300 Combi • Boeing 737-400/400C • Canadian North Fleet • Boeing 737-200 Combi • Later 2019 • Processsing to be done by DMS • Update template
Canadian data, Production and Dissemination • RADAR • 33 sites, C-Band range 240KM to be upgraded to S-Band, 240KM • 5 replaced so far • 7 to be replaced each subsequent year • Data exchanged internationally use the ODIM_H5 format • The format is expected to change to the WMO (emerging) standard CfRadial 2.0 which is based on CF Conventions (NetCDF 4).
Canadian Radars : original network Non-Doppler range: 256 km Doppler range: 112.5 km
Canadian Radar Renewal project S-band range 240 km 2023 Two new S band Sites
Canadian Radar Renewal project : actual status 28 C-band: range 240km, Dedicated Doppler range 150km 5 S-band: range 240 km
Canadian data, Production and Dissemination • Collaborative Monitoring ( used to be NON) • 18 different networks • Mix of governmental and private networks • Total of ~3000 stations • Mostly hourly, TT, P, Wnd, Precip
