  10. EUMETCast Status Report

  11. Aug 2005: Ku-Band bandwidth increase by 3 Mbps (EPS Global Data dissemination support) Oct 2005: Operational dissemination of Land SAF products (products of preceding trial dissemination phase) Dec 2005: Signature of contract for EUMETCast South America Service Dec 2005: Start of operational dissemination of the OSI SAF (KNMI) product “Surface Wind Vector” Dec 2005 Start of test dissemination of ERS SCAT data (in EARS, precursor to EARS ASCAT Service) Jan 2006: Start of EUMETCast South America Service Feb 2006: Start of trial dissemination of the new OSI SAF (Norway) product “North Hemisphere Sea Ice” Activities and Events

  12. South America remains the most significant area imaged to which Met-8 data is not disseminated - particularly Brazil with the same viewing angles like Spain and Portugal MSG-2 LRIT data will be available to South America, but is not suitable for quantitative applications (only half-hourly, 5 out of 11 channels, no HRV, lossy compression) 57th Council meeting (summer 2005) endorsed setting up of the EUMETCast South America service: Pilot service of 3 years Corresponding ITT issued beginning of August 2005, contract signed December 2005, start of service in January 2006, operational acceptance scheduled for March/April EUMETCast Coverage of South America

  13. Service Provider: GlobeCast Spain Communication S/C: NSS-806, 40.5 o West, from NewSkies C-Band, 2.1 Mbps Bandwidth Turn around service (like C-Band Africa Service) Turn around of (only) the High Rate SEVIRI images Turn around reception in Madrid, up-link station near Paris EUMETCast South America Service NSS-806 at 40.5 o W

  17. EUMETCast Provided Services & EKUs – Jan 05 to Jan 06

  18. Pilot EARS-AVHRR ServiceEarly Access

  19. Purpose: To enable Users and Manufacturers to adapt Processing and Visualisation Systems to new products; User Registration started on 9 March – 113 registrations in first week; Trial dissemination via EUMETCast of NOAA-17 and NOAA-18 received at Maspalomas has started. In line with Operational Service Specification in terms of: Product Formatting; Filename Convention; Compression Algorithm; 1-minute Segmentation; EUMETCast configuration details. Pilot EARS-AVHRR ServiceEarly Access (1/2)

  20. Trial dissemination may be interrupted or modified without prior notice. Additional Stations to be added in the coming months Tromsoe expected in April; Kangerlussuaq and Lannion during May/June; Svalbard to replace Tromsoe during Summer; Athens Awaiting resolution of Radio Frequency Interference Problem. Pilot EARS-AVHRR ServiceEarly Access (2/2)

  21. Pilot EARS-AVHRR ServiceTarget Regional Coverage

  22. Current Operational Users: • European Centre for Medium-Range Weather Forecasts (ECMWF) - since Jan 2003. • NASA Global Modeling and Assimilation Office (GMAO) - since 2003. • Deutscher Wetterdienst (DWD) – since Nov 2003. • Japan Meteorological Agency (JMA), Arctic only - since May 2004. • Canadian Meteorological Centre (CMC) – since Sept 2004. • US Navy, Fleet Numerical Meteorology and Oceanography Center (FNMOC) –since Oct 2004. • UK Met Office – since Feb 2005. • National Centers for Environmental Prediction (NCEP) and the Joint Center for Satellite Data Assimilation - since Nov 2005. • NCAR Antarctic Mesoscale Model (AMPS) MODIS Winds in NWP

  23. MODIS Polar Winds Real-Time Processing Delays - Frequency of Delays in Wind Retrievals With an average delay of 3-5 hours, MODIS winds do not meet the 3-hr (or less) cutoff for early model runs. Possible solution: Generate winds with direct broadcast data, either on- or off-site. Processing times are for the middle image in a 3-orbit triplet. Actually processing time from image acquisition to availability of wind vectors is 100 minutes (1.67 hrs) less than shown.

  24. MODIS Data Acquisition Time Bent-pipe McMurdo

  25. A polar winds system was installed at Tromsø, Norway, at the Kongsberg Satellite Services (Ksat) facility in February 2006. The MODIS data are currently acquired with the Integrated Program Office (IPO, the NPOESS people) antenna on Svalbard. At present, wind generation if from Terra only and is irregular due to antenna scheduling issues. Tromsø, Norway

  26. Tromsø Winds As with McMurdo, the wind quality is essential the same as the bent-pipe winds. Processing time is 10-15 minutes longer, however, because the low-level processing system is different and images are larger.

  31. First CGS(-2) output of ATOVS L1NOAA 18, 11/01/2006 13h41 – 15h27 UTC: Ackermann, 2006

  32. Exact timeline is currently being refined: as such the information provided here is indicative only. An updated timeline will be available before end-April. HRPT link to be switched on by Day 2 of Satellite In-Orbit Verification (SIOV) Phase (5 days after launch). Check-out of link will be finished by end of Week 1 of SIOV. The current planning for the SIOV timeline is indicated on next slide. Note that the blue bars indicate that the instrument is in its nominal measurement mode. Data will also be available intermittently during mode check-outs (red bars). Not shown is the data availability of the AVHRR Visible Channel: already available at end of Week 1 of SIOV (will be included). Overview of Planned HRPT Data Availability

  33. CGS BASELINE PRODUCTS INCLUDE: All level 1 Products from all NOAA & Metop sensors Selected Level 2 Products: Temperature/Moisture Profiles, Cloud Products... New level 2 products to be implemented Soil moisture (ASCAT) Polar winds (AVHRR) NDVI (AVHRR) VARIETY OF SERVICES/LEVEL 2 PRODUCTS FROM 7 SAFs: Ocean & Sea Ice Support to nowcasting & VSRF (SW Packages) Ozone Monitoring GRAS Meteorology Climate Monitoring Land Surface Analysis NWP EPS Product Services

  35. Plan for validating PPFs • Detailed planning for validation of the individual PPFs available (see schedule) • Availability of verified (Geometry, Radiometry) products after launch: • Level 1 products • AVHRR: 2 months after launch • ATOVS: 4 months after launch • IASI L1 : 5 months after launch • ASCAT: 4 months after launch • GRAS : 2 months after launch • L2 products: • ATOVS : February 2007 • IASI L2 : December 2006 • Note 1: These dates are likely to be earlier, since we plan to provide products as soon as they are in reasonable bounds after instrument switch on (caveat: not declared operational) • Note 2: HRPT data will be available to Users as soon as instruments are switched on, however quality may be degraded

  36. Dissemination of EPS Global Data via EUMETCast Replacement of baseline Near Real Time (NRT) system Past activities: In 2004, related analysis, preliminary design, feasibility testing and planning performed in an OPS Project Approval by 56th Council Meeting in December 2004 of extension of EUMETCast from 2006 - 2008 to include EPS Global Data dissemination Implementation Project “EPS-EUMETCast Convergence” set up in January 2005 Additional Bandwidth in Ku-Band: 3 Mbps (permanent) from August 2005, additional to 4 Mbps for the existing/operational services) 12 Mbps permanent/total from 1 April 2006 on Status of EPS-EUMETCast Convergence (EEC)

  37. Jan/Feb Final configuration and testing of a Reference EUMETCast Terminal supporting the full 12 Mbps data stream, including full product reconstruction S/W Jan/Feb Delivery and installation of Reference EUMETCast Terminals to SSST (ESTEC), CLS Argos and IASITEC (CNES/Toulouse) Jan - April Implementation and testing of new releases of TelliCast Server (up-link) and Client (EUMETCast Terminal) S/W => bandwidth management AR and bandwidth sharing Feb - June Dissemination of EPS Global Data originating from the EPS GS (V&V and Ops Scenarios Testing) July - … Dissemination of Live Metop EPS Global Data EEC Activities

  38. The activities are on target to enter the final pre-launch phase. No significant, single blocking point has been identified affecting launch critical elements of the system. However: The AMSU-A1 instrument has to be replaced The Metop CFS SW must be patched to correct the PMC SW problem found during SSVT A new MCS version must be installed Regression testing approach for latter elements must be defined/finalised A number of system evolutions need to be completed during rehearsals. The rehearsals themselves present quite a challenge in this environment. Current launch date 17 July 2006 EPS Programme Team Assessment
