Third Party Services enhanced with the deployment of ATOVS and AVHRR Pre-Processing Package (AAPP) version 8.3

The AAPP has been improved in order to synchronise products from FengYun-3 (FY-3) with those disseminated by the China Meteorological Administration (CMA).

Thursday, 24 January 2019

Main changes include:

  • IRAS (Infra Red Atmospheric Sounder) L1B products now use WMO BUFR sequence 3 10 072
  • MWHS (Micro-Wave Humidity Sounder) L1B products now use WMO BUFR 3 10 071. This also means that the subsets with individual messages are organised differently.

The AAPP update also comprises the following minor changes:

  • The software identifier contained in Metop AMSU-A, HIRS and MHS products has been updated to 803.
  • The international data sub-category and data sub-category for NOAA-20 CrIS products have been corrected to signify the correct instrument.
  • Timestamps are now encoded with greater precision.
  • All FY-3 products have been updated to use BUFR master table version 30.

These changes will affect both global and regional products from 13 March 2019.
