Microwave Imager Pre-processor (MWIPP)

Current version: v1.2, February 2023
MWIPP is a software package that has been developed to process microwave imager data from several different instruments. The first release of the package (version 1.0) handles SSMIS, AMSR-2, GMI and MWRI data. Update releases have extended the scope to process simulated data from MWI and ICI on the Metop-SG-B satellite series, due for first launch in 2025 (see this EUMETSAT announcement). Consideration will also be given to supporting other instruments such as AMSR-3 and MTVZA-GY.

MWIPP incorporates relevant functionality from the SSMIS-PP deliverable, namely the ability to ingest BUFR data, perform spatial averaging and create output BUFR files. In addition, it is able to ingest native-format hdf5 files for AMSR-2, GMI and MWRI, optionally map the brightness temperatures to a user-defined grid (e.g. NWP grid), and create output files in BUFR or hdf5 format.
