CSPP Geo AIT Framework Version 2.3.1 Release

3 Sep 2025

The production release of the Version 2.3.1 CSPP Geo Algorithm Integration Team (AIT) Framework package processes Level 1B (L1B) Advanced Baseline Imager (ABI) data from the GOES-16, GOES-17, GOES-18 and GOES-19 satellites, and generates Level 2 (L2) derived geophysical products.

The Version 2.3.1 production release includes the following changes since the Version 2.3.0 production release:

  • The NOAA science algorithms for Aerosol Optical Depth and Cloud Mask updated to the latest versions.
  • Bug fix for rare issue affecting download of ancillary data.

Recommended system requirements for the CSPP AIT Framework software are as follows. This system will allow generation of the full set of Version 2.3 products for all image times. Legacy machines can still be used but will be unable to generate the full set of v2.3 products.

  • AMD Zen 3 generation CPU or Intel equivalent (Intel Rocket Lake Xeon processor generation, circa 2021) or newer, 48 physical cores (e.g. 2 x 24-core), 2.8GHz.
  • 256 GB RAM
  • Rocky 8 or Rocky 9 64-bit Linux (or other compatible 64-bit Linux distribution),
  • 25 TB disk space (does not include long-term storage), capable of a sustained 130 MiB/s random write speeds.

An internet connection is required to download dynamic ancillary data. The expected volume of dynamic ancillary data is about 4.4 GB per day (all products) or 2.6 GB per day if Low Cloud and Fog is excluded.
