AAPP-SG<\/h2>\n


\nThe ATOVS and AVHRR Pre-Processor – Second Generation (AAPP-SG) is a software package designed to process sounder data from the MWS and IASI-NG instruments on the Metop-SG satellite series. See Oscar Space – EPS-SG<\/a>.<\/p>\n

The Digital Object Identifier (DOI) of the package is: 10.15770\/EUM_SEC_CLM_1012<\/strong>.<\/p>\n

AAPP-SG version 1.0.0 is the first major release. It is compatible with the EUMETSAT pre-launch simulated test data in netCDF format, available at metop-sg-test-data<\/a>. In particular the “MWS test data version 3” and the “IASI-NG test data L1C and L1D version 2.1”. It is also compatible with the MWS test data in BUFR format linked from the same web page.<\/p>\n

AAPP-SG is compatible with post-launch data for MWS and IASI-NG in netCDF format. However, the IASI-NG L1C and L1D BUFR sequences are still not finalised. Further changes are anticipated to bring AAPP-SG into line with EUMETSAT’s operational dissemination.<\/p>\n
