The first version of a new deliverable, IRSPP, has been released. This is a package that will be used for processing data from the InfraRed Sounder on the MTG-S satellite series, due for first launch in 2024. This software release is intended to familiarise users with the package, which is compatible with simulated test data already made available by EUMETSAT. For more details, please see the IRSPP web page.
