AAPP and other processing tools


Nigel Atkinson from the UK MetOffice presents the AAPP package to process ATOVS and AVHRR data. Some processing and visualisation examples are given.


The ATOVS and AVHRR Pre-processing Package (AAPP) is a tool to process sounder and imager data from the NOAA, Metop and FengYun polar orbiting satellites. It was originally developed in the late 1990s to support processing of direct broadcast data from the NOAA-POES satellites, and has since been extended to accommodate Metop (including IASI) and more recently Suomi-NPP. The package is maintained by the EUMETSAT Satellite Application Facility for Numerical Weather Prediction (NWP SAF). An overview will be given of the capabilities of AAPP, including how it complements other processing packages such as IMAPP and CSPP. AAPP products include calibrated, re-mapped radiances (for NWP) and derived products such as cloud mask. Examples of the products and their uses will be shown.
