How to build, deploy, and run Metopizer, AAPP, and OPS-LRS in a Singularity container Liam.Gumley@ssec.wisc.edu 2019/08/12 Metopizer is used to transform Metop Level 0 packet files into the EPS Level 0 format required by AAPP and OPS-LRS. AAPP is used for NOAA and Metop AVHRR and ATOVS processing. AAPP and OPS-LRS are used for Metop IASI processing. To build and deploy Metopizer, AAPP, and OPS-LRS in a Singularity container see the README file in the build directory. To run NOAA-18/19 and Metop-A/B/C test cases, see the test.sh script in the test directory. Before you run the test script you must first define the AAPP_DIR environment as shown below: export AAPP_DIR=$HOME/aapp_singularity # modify to match your own installation directory export PATH=$PATH:$AAPP_DIR/scripts
