############################################################################## # # # ATOVS and AVHRR Preprocessing Package (AAPP) # # Version 6.11 Release Notes # # 26 October 2009 # # # ############################################################################## 1. Package contents ------------------- The following files are contained in this update release (with file sizes in bytes): RELEASE_NOTE_AAPP_6_11.txt 3426 This release note AAPP_update_6_11.tgz 29419 Source code and data This is an incremental update; users need to have installed version 6.1 and updates 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9 and 6.10. 2. Purpose ---------- - Routine updates to AMSU calibration parameters for NOAA-15 and 16 - Allow for recent degradations in NOAA-19 MHS - Option for HIRS calibration to be skipped - e.g. for NOAA-15 (see section 6) - Additional decommutation tool for "packed" HRPT files - Minor bug fixes 3. Installation --------------- a. Copy the tgz file to your AAPP top directory (i.e. the directory containing AAPP, metop-tools and iasi-tools) b. Unpack it using the command tar -xvmzf AAPP_update_6_11.tgz or if your system does not support the "-z" option in tar, use gunzip -c AAPP_update_6_11.tgz | tar -xmf - c. Go to the AAPP_6 top directory and type make 4. License ---------- To use this software, users need to have registered for AAPP v6 with the NWP SAF (www.nwpsaf.org), and to have agreed to the terms of the license agreement. 5. Version control information ------------------------------ The source package (AAPP_update_6_11.tgz) corresponds to Subversion Revision 169 in the AAPP repository held at the Met Office. 6. Detailed list of changes, rev 158 to 169 --------------------------- Key: M=Modified, A=Added, D=Deleted Decommutation ============= A AAPP/src/decommutation/bin/unpack_noaa_hrpt.F A AAPP/src/decommutation/bin/unpack_noaa_hrpt.ksh M AAPP/src/decommutation/bin/Makefile Tool to unpack NOAA HRPT files containing packed 10-bit words. Can be customised according to station format. Calibration =========== M AAPP/src/calibration/libamsuacl/amsua_clparams.dat M AAPP/src/calibration/libamsubcl/amsub_clparams.dat Gross limit updates for NOAA-15 AMSU-A/B and NOAA-16 AMSU-B M AAPP/src/calibration/libhirscl_algoV4/hclin_algoV4.F Initialise hrs_cllgu whether or not calibration option is selected. Tools ===== M AAPP/src/tools/bin/AAPP_RUN_NOAA.ksh Bug fix: aman.l1d was not re-named on completion. Allow ${HIRSCL_VERSION} to be satellite dependent, through use of new environment variable HIRSCL_SAT. If the version number is >1 then HIRS calibration is skipped - required for NOAA-15 after 1 June 2009, e.g. HIRSCL_VERSION="1 99"; HIRSCL_SAT="default noaa15"; export HIRSCL_SAT Preprocessing ============= M AAPP/src/preproc/libatovpp/ppbind.F For NOAA-19, do not set Bqc(bit0) if MHS channels 3/4 missing M AAPP/src/preproc/libatovpp/LUT.fdf Avoid rounding error that can cause inter-platform differences in NOAA-17 AMSU to HIRS mapping (causing false alarms in RARS monitoring).
