  1. Volker Gärtner Marianne König (Volker.Gaertner@eumetsat.int) (Marianne.Koenig@eumetsat.int) EUMETSATContributions to COPS

  2. EUMETSAT Contribution to COPS During the COPS Operations Period EUMETSAT is providing the following data streams • Nominal Meteosat and Metop operational services • Extra image data from the trial Rapid Scanning Service • Extra Meteorological Product (GII on pixel basis)

  3. EUMETSAT Meteosat Configurations in 2007 • MET-9 at 0° takes over the prime service from Met-8 on 11 April 07. • MET-8 at 3.4°W becomes backup satellite for the prime service on 11 April 07. After 10 May 07, will start RSS preparation. It will be relocated to 9.5 °E in Jan 08. • MET-7 at 57.5°E carries out the Indian Ocean Data Collection service. • MET-6 drifting to 67.5°E in support to MET-7 for the IODC DCP acquisition in eclipse. Stop manoeuvres planned on 26 April 07. MET-6 co-aligned with MET-7 beginning of April 07.

  4. EUMETSATRapid Scaning Service

  5. Meteosat Image Taking • 100 rpm spinner • Scan – step mechanism • 1500 scan lines in 15 minute • (1 baseline repeat cycle) • 1250 for forward scan lines

  6. What is ‘Rapid Scanning’ • For MSG we normally scan the full Earth disc every 15 minutes • To increase the temporal resolution (i.e. to decrease the time between scans) we can opt to scan a smaller area more frequently • This is ‘Rapid Scanning’ (it could also be called ‘Reduced Scanning’)

  7. With MSG we can scan in 15 minutes either: The full disc The same reduced area several times 15 minute scan of the full Earth disc 3 x 5 minute scan of the top 1/3 of the Earth

  8. MSG Rapid Scanning during COPS Experiment • It is planned to introduce an operational MSG Rapid Scanning Service (RSS) by the second quarter of 2008 • During summer of 2007 an intensive test and validation period to prepare for the operational RSS service is conducted • This validation period coincides with the COPS operational period (June, July & August of 2007) • It is a best effort activity to be as continuous as possible, but no service commitment can be made

  9. Rapid Scanning Trials During 2007 • 24 hour rapid scanning tests made during MSG-1 and MSG-2 commissioning – results were largely OK • First extended rapid scanning trial (with Met-9 at 0 degrees) took place between 12-19 February 2007 - results look reasonable • Next extended trial (2 weeks) is planned for May using Met-8 at 3.4°W • Long continuous tests will coincide with COPS experiment • It looks as if it will be possible to perform almostcontinuous rapid scanning for the 3 months, but it will at least need a 1-2 day interruption every month • Should there be a need to modify the spacecraft procedures or to reconfigure the ground segment EUMETSAT reserves the right to do so

  10. Nominal Meteosat Scan (15 minutes)

  11. Rapid Meteosat Scan (5 minutes)

  14. Nominal Meteosat Scan (15 minutes) - HRV

  15. Rapid Meteosat Scan (5 minutes) - HRV

  16. Data provision during COPS • Nominal Meteosat-9 Images will be disseminated via EUMETCast. • Nominal MPEF products will be disseminated via EUMETCast. • High resolution GII will most likely be available via FTP. • Radid Scan Images of Meteosat-8 will be disseminated via EUMETCast (subject to ground segment configuration). • All historic Image Data and Products are available from the EUMETSAT archive. Online ordering via the EUMETSAT Web Site (www.eumetsat.int).

  17. Interesting Products for Nowcasting - GII • The Global Instability Indices (GII) Product: • A number of (empirical) instability indices are computed from the MSG image data, together with forecasted temperature and humidity profiles. • These indices describe the potential for convection during still cloud-free conditions. • The GII product includes e.g. the Lifted Index, the K-Index, and Total Precipitable Water

  18. Global Instability Indices K - Index • Operational EUMETSAT Product COPS Product 15 x 15 Pixel Resolution 1 x 1 Pixel Resolution

  19. Global Instability Indices Precipitable water • Operational EUMETSAT Product COPS Product 15 x 15 Pixel Resolution 1 x 1 Pixel Resolution

  20. High resolution GII during COPS • For the COPS experiment it is planned to produce the GII product for the European area on a pixel basis. • The product will be made available in near real-time. • The distribution mechanism will most likely be via FTP service.

  21. Metop data provision during COPS • During the time of the COPS campaign the Metop data will be available in near real-time via direct reception (HRPT receiving stations). • The global level 1b and level 2 products will be available via EUMETCast. • All historic Metop data are available from the EUMETSAT archive. Online ordering via the EUMETSAT Web Site (www.eumetsat.int).

  23. EUMETCastthe EUMETSAT Data Dissemination Service

  24. EUMETCast Technical Approach & Standards • Generic, multi-mission dissemination systems based on standard DVB multicast technology • Uses commercial broadcast channels on TV, DTH telecommunication satellites • Off-the shelf, commercially available reception equipment • IP over DVB standard coding • Transparent transfer of files, i.e. files received exactly as sent • Use of standard formats/encoding - XRIT, BUFR, GRIB, HDF … • Secure access control at individual file and group of Users level • Open, flexible, scalable architecture

  25. EUMETCast Overview

  26. EUMETCast Coverage

  27. Generic EUMETCast Solution Hardware Recommendations • Recommend separating the procurement of hardware from the software • Items could be sources separately – local procurement of hardware • More flexible maintenance approach • Easier to upgrade individual items of the reception station • Recommend operating with 2 PCs • First for reception of the DVB signal (running the TELLICAST software) and any housekeeping activities • Second for any application software and further data processing • If a user has low processing/data needs, a single PC could be used • RAM Disk for the TELLICAST file database buffer • Optimal antenna size EUMETCast-Africa (2.4m) • User-friendly set-up

  28. Generic EUMETCast Solution • EUMETCast (DVB) Standard Hardware - indicative costs LNB/Feedhorn, Antenna 200 EUR 2 x PC, Hard Disk, Ethernet 2000 EUR DVB PCI Card 100 EUR EUMETCast Client Software 60 EUR EUMETCast Key Unit (EKU) 40 EUR Total (2 PCs) 2400 EUR 1400 EUR Total (1 PC)

  29. Generic EUMETCast Solution • Software Requirements Auxiliary software • Operating software (Windows or Linux) - included within the cost of PC • Housekeeping software – included in cost of application software, or available as freeware

  30. Generic EUMETCast Solution Application software – depends upon users needs • Ensure range of satellite & instruments data covered matches your needs • Processed Products and in-situ data can be received/displayed • Accepts a range of standard formats from the variety of input data • Range of processing matches current and foreseen needs: • Projection, Landmarks, Calibration, Logs & Reports • Adequate Display Function: • Quick-Look, Zoom & Pan, Animation, Overlays, Histogram, Pixel Analysis. • Colour Table, RGB Comparisons • Meteorological displays: • Cloud development, cloud analysis • Forecasting displays • User-friendly software
