• Met-9 drift start


• Met-7 direct dissemination stops on 14 June 2006• Met-9 enters Operational Service at 0° on 1 Aug 2006• Met-8 stops dissemination on end September 2006• Met-7 starts the IODC mission early Dec 06• Met-5 stops imaging and supports the DCP mission in eclipse• Met-6 stops the RSS service on 31 Dec 2006• Met-5 is re-orbited in late April 07• If DCP testing on Met-8 is successful, Met-6 is relocated at 63°E

to support the DCP mission in eclipse• During the Met-7 drift users are likely to experience degraded

performances of RSS. A minor impact is expected on IODC data• Meteosat-8 Rapid Scanning is TBC, earliest expected Jan 2008


MSG-2 Commissioning• On schedule• Image and Product Validation ongoing• Low-frequency modulated noise on 6.2 micron

channel– Induced in pre-amp or other onboard electronics– Possible corrective measures

• Redundant h/w• On ground processing


6.2 micron striping (MSG-1 vs MSG-2)

• Current lifetime tests– 1-4 years nominal +3 yrs RSS– 2-7 years RSS– Spindle life test 3 years nominal + 7 yrs RSS (TBC)– Ball Bearings extension test


EUMETCast Status Report


Activities and Events • 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

EUMETCast Coverage of South America• 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 South America Service• 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

MODIS Winds in NWP

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 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.


MODIS Data Acquisition Time

Bent-pipe

McMurdo


Tromsø, Norway

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 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.

Overview of Planned HRPT Data Availability

• 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).

Status of EPS-EUMETCast Convergence (EEC)

• 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


EEC Activities• Jan/Feb Final configuration and testing of a Reference

EUMETCast Terminal supporting the full 12 Mbps datastream, 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 theEPS GS (V&V and Ops Scenarios Testing)

• July - … Dissemination of Live Metop EPS Global Data


EPS Programme Team Assessment• 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


Reprocessing• Support to various activities
