  CSPP Advanced Clear-Sky Processor for Oceans (ACSPO) Software Version 1.0 Release

8 April 2015

First release of the NOAA/NESDIS/STAR Advanced Clear-Sky Processor for Oceans (ACSPO) Sea Surface Temperature (SST) retrieval software for VIIRS, MODIS and AVHRR imagers. ACSPO development is led by Alexander Ignatov of the NOAA/NESDIS Center for Satellite Applications and Research (STAR), in conjunction with John Sapper of the NOAA/NESDIS Office of Satellite and Product Operations (OSPO). This CSPP release was created in close collaboration with John Stroup and Yury Kihai at STAR.

This CSPP release (CSPP_ACSPO_1_0) provides ACSPO version 2.31, adapted and tested for operation in a real-time direct broadcast environment. The software contains binary executable files and supporting static data files, as well as input and output files for verification of a successful installation.

This package is in support of Direct Broadcast users, and is sponsored by the Community Satellite Processing Package (CSPP) project funded by the NOAA/NASA Joint Polar Satellite System (JPSS).

System requirements for the CSPP_ACSPO v1.0 software are as follows:
  • Intel or AMD CPU with 64-bit instruction support,
  • 8 GB RAM,
  • CentOS-6 64-bit Linux (or other compatible 64-bit Linux distribution),
  • 5 GB of disk space (plus space for your own DB data and CSPP_ACSPO products).
Supported satellites, sensors, and data include:
  • Suomi NPP VIIRS SDR (from CSPP or CLASS),
  • NOAA-15,16,17,18,19 and Metop-A,B AVHRR (from AAPP v7 or CLASS),
  • MODIS Aqua and Terra L1B (from IMAPP or NASA LANCE/LAADS).
The CSPP ACSPO software generates two netCDF4 output product files, which contain similar information. The two files are a result of continuing a legacy format, and the addition of a GSD2 format, following a set of conventions specified by the Group for High Resolution Sea Surface Temperature (GHRSST). Complete installation, execution and product information is included with the release.
