Please note that the AAPP Supplementary Downloads files (including test cases, IASI files, MAIA files) were recently moved over to a EUMETSAT ftp server. The links have now been updated in page https://nwp-saf.eumetsat.int/site/software/aapp/download/. We apologise if you have been unable to access the data.
If you are using the get_aux_files.sh script (for automatic download of IASI auxiliary files), you will need to download a new version of this script as the old version was incompatible with the new file locations. It is available at ftp://ftp.eumetsat.int/pub/NWPSAF/aapp_data_files/OPS-LRS/aux_data/get_aux_files.sh.
Also, we have updated the install_aapp8.sh script, at ftp://ftp.eumetsat.int/pub/NWPSAF/aapp_data_files/install_aapp8.sh (it now refers to AAPP v8.2 and ecCodes v2.8.2).

Nigel
