2 RARS-IG Oct 2012© Crown copyright Met Office AAPP AAPP versionDateApplicability to RARS March 2012Initial release of AAPP v7. Supersedes v6. First with NPP capability July 2012Fix NOAA-18 AMSU-A processing Add Metop-B Oct 2012Fix NOAA-15 AMSU-A processing Fix EARS-IASI PCs Improve ATMS/CrIS processing Add FY-3A/B MWHS/MWTS BUFR encoding OPS-LRS_v6- 0+p12 27 July 2012Recommended version for IASI processing 7.4 beta (not officially released) 17 Oct 2012A patch file is available to fix other issues: Metop-B MHS instrument I/D was wrong in AAPP code (see forum announcement) CrIS channel selection bug, and improve BUFR encoding Fix problem in BUFR encoding FY-3B MWTS/MWHS

4 RARS-IG Oct 2012© Crown copyright Met Office Metop-A bias issue Metop-A ATOVS being disseminated by EARS stations, and also by Kiyose, Jincheon and Hong Kong. Not available to South America; limited coverage of Australia AMSU bias issue recently identified by Météo-France (next slide)  2 sets of antenna corrections are defined in AAPP: the original set and a post-launch update  EARS and Kiyose had been using v2, Jincheon and Hong Kong were using v1  Jincheon switched to v2 on 12 th October, Hong Kong on 22 nd October export FDFSAT=METO-02 export FDFVN=2  This was not picked up by the NWP SAF monitoring because we can accept either version. Should not arise for Metop-B (only 1 set of corrections)  But global Metop-B BUFR from EUMETSAT has version number set to 2 – this number is not satellite specific at EUMETSAT?

6 RARS-IG Oct 2012© Crown copyright Met Office Metop-B Changes to accommodate Metop-B: 1.Check: has your station correctly extracted OBT-UTC correlation parameters from the MMAM? 2.Install AAPP v7.3 3.In ATOVS_ENV7, add M01 to list of satellites in PAR_NAVIGATION_DEFAULT_LISTESAT and PAR_NAVIGATION_DEFAULT_LISTEBUL 4.install MHS patch (see “7.4 beta” in earlier table) AMSU, MHS, HIRS, AVHRR all working L0 data for 16/10/2012 from Judd Taylor, Orbital Systems

7 RARS-IG Oct 2012© Crown copyright Met Office Extension of RARS to IASI The EUMETSAT EARS-IASI service is already operational, Athens, Maspalomas, Lannion, Svalbard Uses OPS-LRS + AAPP 366 channels Principal Components, all spots Output BUFR file typically 12Mb per pass  Sequence Athens pass

8 RARS-IG Oct 2012© Crown copyright Met Office Extension of RARS to Suomi NPP For level 0 to level 1 processing, use Univ. Wisconsin’s Community Satellite Processing Package (CSPP) Current version v1.2 (4 th Oct 2012) Needs a reasonably powerful Linux system (64 bits; 16 GB memory) AAPP ingests the Sensor Data Record (SDR) files for ATMS/CrIS. These are HDF5. Converts to BUFR  Sequence for ATMS; for CrIS  Master table 16 (WMO web site) 399 channels baseline for CrIS Most of the functionality is in AAPP v7.3. A few fields are not yet filled for CrIS (e.g. surface height and type; cloud cover). This will be addressed.

9 RARS-IG Oct 2012© Crown copyright Met Office Extension of RARS to FY-3 Sounder instruments in the L-band direct broadcast Level 0 processing package for FY-3A and FY-3B available from CMA: Training → FAQs Generates SDRs (same HDF5 format as global data already distributed by EUMETSAT) BUFR encoding for MWTS and MWHS instruments now implemented in AAPP – based on sequence devised by ECMWF (not yet addressed IRAS) Submit proposal to WMO Codes group? There will be strong interest in FY-3C with an AMSU-like microwave sounder (launch Sept 2013).

10 RARS-IG Oct 2012© Crown copyright Met Office NWP SAF RARS monitoring No changes to RARS-ATOVS monitoring at Met Office Daily stats files ed to those centres who have requested them Plots available at Met Office (EARS, A-P RARS, S-A RARS) and Météo-France (EARS) Monitoring of GTS data availability is still planned. (Currently monitor data received via ftp)

13 RARS-IG Oct 2012© Crown copyright Met Office EARS-IASI monitoring (Met Office) Compare raw radiances with reconstructed Until 23 October, getting some bad PC scores (see below). Should be fixed now that AAPP v7.3 is implemented at EARS nodes

14 RARS-IG Oct 2012© Crown copyright Met Office Daily EARS-IASI log files Plan to make these available to EUMETSAT Also plan comparisons with global data stn orbit scans %band1 %band2 %band3 sva sva sva sva sva ath sva lan ath mas sva lan mas sva mas
