2. RARS Implementation Group – Sixth meeting Exeter - 2012 EARS-IASI

3. RARS Implementation Group – Sixth meeting Exeter - 2012 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 - 2012 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 2012. 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.
