Microwave Imager Pre-processor (MWIPP)

Current version: v1.3, August 2026
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 October 2026 (see this ESA article). MWIPP version 1.3 includes support for AMSR-3.

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 (and netCDF for MWI/ICI/AMSR-3), optionally map the brightness temperatures to a user-defined grid (e.g. NWP grid), and create output files in BUFR or hdf5 format.
