IMAPP MODIS Level 2 Version 3.1.1 Patch

Post by kathys »

Dear Colleagues,

A Software Patch has been created for the NASA International MODIS/AIRS Processing Package (IMAPP) MODIS Level 2 Version 3.1 product (MODIS Atmosphere Collect 6) software. This patch improves the performance of Terra MODIS retrievals after the Terra Safe-Hold event that occurred in 2016 (please see:
https://mcst.gsfc.nasa.gov/sites/mcst.g ... ides_0.pdf for more information).

The IMAPP MODIS Level 2 Version 3.1.1 patch includes MODIS atmosphere group updates to the Terra destriping coefficients, Terra MODIS cloud mask threshold files and along with it, updated cloud mask statically compiled binaries. In addition, a few corrections were made to ancillary data fetching scripts.

The Patch can be installed over your existing installation by following the instructions below. In the example, the imapp_modisl2 installation directory is ${HOME}/imapp_modisl2.

1). Download the IMAPP MODIS Level 2 Version 3.1.1 Patch (6.8 MB):

cd ${HOME)
wget ftp://ftp.ssec.wisc.edu/pub/IMAPP/MODIS ... TCH.tar.gz

2). Install the software on top of your existing installation

tar zxvf IMAPP_MODISL2_V3.1.1_PATCH.tar.gz

3). Confirm your successful patched installation (Version 3.1.1)

cat imapp_modisl2/version

IMAPP MODIS Level 2 version 3.1 Patch v1.0


For those using the IMAPP Direct Broadcast Virtual Machine (DBVM), a new version of the DBVM that includes the patched MODIS Level 2 v3.1 software will be released in the next few days.

Please let us know if you have any comments, questions or concerns.
