CSPP ACSPO SST V1.1.2 Software Patch

Post by kathys »

Dear Colleagues,

A required dynamic ancillary input dataset used by the CSPP Version 1.1 NOAA/STAR Advanced Clear-Sky Processor for Oceans (ACSPO) Sea Surface Temperature (SST) retrieval software is being replaced, and therefore a patch is required. CSPP is the NOAA sponsored Community Satellite Processing Package. ASCPO software supports SST retrievals from direct broadcast VIIRS SDR, and AVHRR and MODIS Level 1B inputs.

The dynamic Canadian Meteorological Center (CMC) 0.2 degree global sea surface temperature analysis files have been discontinued and replaced by 0.1 degree files. A patch has been created (ACSPO v1.1.2) to use the new 0.1 degree files and to include a runtime option that allows use of the 0.2 degree files for historical data processing (datasets prior to 1 January 2017). The results show no significant impact on the SST end product.

In addition, the patch includes improvements to the lftp ancillary file download settings that make it more robust.

Please follow the instructions below to update the CSPP ACSPO v1.1 software package on the computers where they are installed. Linux terminal commands included in these instructions assume the bash (Bourne) shell is used.

cd $CSPP_ACSPO_HOME
wget ftp://ftp.ssec.wisc.edu/pub/CSPP/acspo_ ... tch.tar.gz
tar xvf CSPP_ACSPO_V1.1.2_patch.tar.gz

Confirm your updated execution script:
$CSPP_ACSPO_HOME/scripts/run_acspo.bash

which should now include this runtime option:

-r CMC_RES, --ghrsst=CMC_RES
Resolution of CMC GHRSST ancillary data files to use
[default: 0.1 (deg) from 1-Jan-2017, 0.2 before]


Please feel free to contact us with any comments or questions you may have.
