Overview• Current Systems

– Meteosat First Generation– Meteosat Second Generation

• Future Systems– EUMETSAT Polar System

• Additional– EUMETCast– EUMETSAT ATOVS Retransmission System– JASON-2


Meteosat First Generation(until end of 2008, TBC by Council)

• Three operational satellites• Meteosat-7 (Parallel Operations to MSG, Until Early 2005)• Meteosat-6 (Rapid Scan Service, Until End 2005)• Meteosat-5 (Indian Ocean Data Coverage)

• Services• Image Acquisition, Rectification and Dissemination• Data Collection and Re-transmission (Only 0o)• Meteorological Data Distribution (Only 0o)• Meteorological Products Extraction

• Rapid Scan Products (Only 10oW, best effort basis) • Reprocessing facility


Meteosat Second GenerationMeteosat-8

• Commissioning finished in December 2003• Regular Operations commenced in January 2004• Operational name is Meteosat-8• MSG-2 launch foreseen early 2005


Meteosat Second GenerationMeteosat-8

• Image and Product validation phase-out– Until end of February 2004

• Status nominal– Calibration within spec

• BB-calibration timing impact (mirror angle dependency)• e.g. within 1K with HIRS

– Rectification nominal– Main anomaly: SSPA failure -> transponder limitation

• Dissemination via EUMETCast– Dedicated land-line to Wallops

EUMETSAT Polar System

Current Status• SVT in May 2004 successful• 1st GS delivery III/2004• Final GS for launch end of 2004• Launch end of 2005• Schedule risk mitigation TBC


Instrument processing chain status• IASI

– L1 CNES– Working (I/F, data)– L2 open

• ATOVS– Performance issues with L2, situation improved with RTTOV

• GOME-2– L1 FAT ongoing

• GRAS– POD and POD Val clarified

• ASCAT– L1 FAT completed


Additional

• Information package released on the WEB– Test data and tools to be included sequentially

• PPF Labs to be delivered sequentially – QCF and ASCAT already in house


EPS Data dissemination

• Current Baseline NRT– Dedicated line to US

• Baseline format EPS native• User request for dissemination via EUMETCast• Data to be provided in WMO standard formats

(BUFR etc).


EUMETCast

• Channel allocation:– Channel 1 EARS & RSS 0.250 Mbps– Channel 2 MSG HRIT 1.620 Mbps– Channel 3 MSG LRIT 0.386 Mbps– Channel 4 DWDSAT 0.256 Mbps

• Channel 2 and 3 are fed into the C-band turn-around service.

• C-band bandwidth is 2.7 Mbps• Scope and constraints for additional bandwidth

EUMETCast Service Extensions Envisaged (I)

• Evolution of Meteosat-8 meteorological products– New products based on prototyping by MET– Updates of existing products based on operational experience

• VEGETATION derived products– VEGETATION products from SPOT– Proposal by European Commission for an operational

demonstration in the second half of 2004

• Basic meteorological Data from WMO regional Association VI– RA VI is Europe and Middle East– Use of EUMETCast for basic provision of observations and forecasts– Working Group under RA VI is establishing user requirements– Formal proposal to EUMETSAT delegate bodies will follow


EUMETCast Service Extensions Envisaged (II)• ENVISAT data

– Interest in ENVISAT data in Africa (MERIS for fishery)– Informal communication with ESA

• AEOLUS data – ESA Wind lidar mission to be launched 2007– Informal communication with ESA

• Indian satellite data (INSAT, KALPANA)– Backup to Meteosat-5 data

– To be provided via NOAA and Météo-France• Meteosat-8 reception in South America

– Sub-Continent not covered by EUMETCast– Options under investigation


EARS Services SpecificationObjective To provide the European Meteorological Community with ATOVS

data covering data-sparse areas.

Timeliness 30 min.

Instruments AMSU-A, AMSU-B, HIRS/3, AVHRR for local cloud informationFull AVHRR data set will not be distributed

ProcessingLevel ofRetransmittedProducts

AMSU-A AAPP level 1a and 1c on AMSU-A gridAMSU-B AAPP level 1a and 1c on AMSU-B gridHIRS/3 AAPP level 1a and 1c on HIRS/3 gridCloud info. Modified AAPP level 1d containing only AVHRR

derived cloud information on HIRS/3 grid

Satellites All operational NOAA satellites

GeographicalCoverage ofATOVS data

Geographical coverage primarily over data-sparse sea areas aroundEurope as covered by the HRPT stations located in:

Tromsø, Norway; Maspalomas, Spain; Kangerlussuaq, Greenland;Athens, Greece, Dartmouth, Halifax, Canada; Gilmore Creek, Alaska,USA;

EARS Continuation and Extension

• Current EARS pilot phase runs until the end of this year

• Proposal to be put forward to Council already endorsed by STG:

– Continuation of ATOVS Retransmission Service

– New Pilot AVHRR Retransmission Service

– New Pilot ASCAT Retransmission Service– Extended Coverage

Data Products and Services

– Operational Science Data Record (OSDR)• Wind/wave products distributed to users within 3 hours

– Geophysical Data Record (GDR)• 10 days span, same quality as for Jason-1

– Interim Geophysical Data Record (IGDR)• Compromise delay vs accuracy under evaluation

– IGDR + waveform for continental water studies• under evaluation

– Other products• WSOA products• Multi satellite products• Coastal zone products


Data Dissemination and Policy

– Data Dissemination• OSDR distributed by Eumetsat in Europe through GTS and

other such networks (e.g. world wide web)• IGDR distributed by CNES through GTS and other such

networks (e.g. world wide web)• GDR distributed by CNES• NASA/NOAA have similar responsibility on the US side

– Data Policy• All products available through this program will be made

available in accordance with WMO resolution 40 and classified as essential data


JASON-2

• 4-party programme with CNES, EUMETSAT, NASA and NOAA

• Operational continuation of CNES/NASA project JASON-1, satellite launched Dec 2001

• First Critical Design review end of 2004• Decision point for JASON-2B end of 2004

– Operational programme?!

• Current launch date April 2008


Satellite Application Facilities
