2 RARS Implementation Group – Sixth meeting Exeter EARS-IASI

3 RARS Implementation Group – Sixth meeting Exeter EARS-IASI Design: Decentralised processing. Channel selection and data compression using Principal Component Scores to reduce data volume. Processor: AAPP (v7.3) and OPS-LRS (v6.0p12) as delivered by NWP SAF. Distribution via EUMETCast Ku-Band and GTS. Satellites: Metop-A (Metop-B, Metop-C). Number of stations: 4 (more planned for Metop-B). Products, formats: One Level 1c product per pass: –calibrated and navigated IASI observations, –combined product containing both Principal Component scores and 366 original IASI Channels, –cloud/scene analysis information, –BUFR format. Timeliness: 30 minutes (HRPT). 60 minutes (FDES).

4 RARS Implementation Group – Sixth meeting Exeter EARS-IASI (2/2) Number of Users on EUMETCast: > 100 registered Users. Number of products per day: ~ 25 files, corresponding to 500 MB. System evolutions in the near future: GTS dissemination to start in November Metop-B. Product quality monitoring (under development): NWP-SAF product monitoring (comparison with global data and local products, warning messages, etc.). Details to be agreed. Statistics + inter-comparisons at EUMETSAT.

10 RARS Implementation Group – Sixth meeting Exeter EARS-NPP Common part Slide: 10 Geographical coverage:  6 core European stations initially. Other EARS stations to be added if and when NPP data become available. Product processing:  CSPP/AAPP, as provided by the CIMSS/NWP-SAF, configured and run by EUMETSAT. Kangerlussuaq Svalbard Athens Lannion Moscow Maspalomas

11 RARS Implementation Group – Sixth meeting Exeter EARS-NPP EARS-ATMS Slide: 11 Product Segmentation: one file per station pass. Products via EUMETCast (Ku-Band Europe):  SDR (Level 1),  all 22 channels,  all FOV,  data on original instrument grid,  BUFR format. Timeliness via EUMETCast: 30 minutes. Products via GTS/RMDCN: As for EUMETCast.

12 RARS Implementation Group – Sixth meeting Exeter EARS-NPP EARS-CrIS Slide: 12 Product Segmentation: one file per station pass. Products via EUMETCast (Ku-Band Europe):  SDR (Level 1),  399 channels out of 1305,  all FOV,  data on original instrument grid,  BUFR format. Timeliness via EUMETCast: 30 minutes. Products via GTS/RMDCN: As for EUMETCast.

13 RARS Implementation Group – Sixth meeting Exeter EARS-NPP EARS-VIIRS Slide: 13 Product Segmentation: segmented. Duplicates removed. Products via EUMETCast (Ku-Band Europe):  SDR (Level 1), geolocation on tie-points,  all 16 M-Band channels,  HDF5 format,  bzip2 compressed. Timeliness via EUMETCast: 15 minutes. Products via GTS/RMDCN: None.

14 RARS Implementation Group – Sixth meeting Exeter Building on EARS infrastructure Slide: 14 EUMETCast is EUMETSATs data dissemination system based on DVB over satellite Minutes

15 RARS Implementation Group – Sixth meeting Exeter Product Processing Slide: 15 CSPP AAPP L1/SDR ATMS & CrIS VFP** L1/SDR VIIRS GTS EUMETCast L1 BUFR ATMS & CrIS BZIP2 L1’ VIIRS L1’’ VIIRS L0/RDR* VIIRS, ATMS & CrIS *: using RT-STPS to produce RDR per instrument from CADU file containing all instruments. **VFP: VIIRS Formatting Package (computes geolocation on tie-points, scale radiances and segments data)

16 RARS Implementation Group – Sixth meeting Exeter Slide: 16 Product Quality Monitoring Planned for EAR-NPP EARS-ATMS and EARS-CrIS: -Product quality indicator collected during the processing and recorded (statistics, time series…). -Comparison with global data and independent local products (offline). EARS-VIIRS: -As for EARS-ATMS and EARS-CrIS plus: -VIIRS tie-point and interpolation: geolocation errors to be recorded. Involvement of the SAFs (TBC): -NWP-SAF for EARS-ATMS and EARS-CrIS. -NWC-SAF for EARS-VIIRS.

17 RARS Implementation Group – Sixth meeting Exeter Daily Data Volume per Service (October 2012) Estimates for ATMS, CrIS and VIIRS Slide: 17 ServiceNumber of stations Number of satellites Total number of passes Daily volume EARS-ATOVS EARS-AVHRR7228 (630 segments)1400 EARS-ASCAT EARS-IASI EARS-NWC7228 (630 segments)800 EARS-ATMS MB EARS-CrIS MB EARS-VIIRS6114 (300 segments)> 11GB

18 RARS Implementation Group – Sixth meeting Exeter Slide: 18 Early Access to Regional NPP Services Early access to the three Regional NPP Services is expected as follows:  EARS-ATMS starting in Q  EARS-CrIS starting in Q4 2012, initially without VIIRS Cloud information  EARS-VIIRS starting in Q1 2013
