CSPP Geo AIT Framework for ABI

The AIT Framework was developed by NOAA STAR as an integration point for GOES-R Level 2 product algorithms. Reference implementations of most of GOES-R product algorithms currently run in the framework. It has been used for validation of products from the operational system. Currently it is used to generate the operational GOES-R series Low Cloud and Fog products, as well as products for NOAA polar orbiter missions.

The CSPP Geo AIT Framework package processes ABI Level 1 data in the mission-standard NetCDF-4 format, as written by the GRB software package.  Output is written to NetCDF-4 files, in the operational file formats. It generates a subset of the GOES-R enterprise Level 2 products, including imagery and cloud products (see the list below). Note that the while the theoretical basis of the product algorithms is the same as those in the operational ground system, users should not expect an exact match in products because of differences in implementation.

List of Products:

  • Clear Sky Masks
  • Cloud and Moisture Imagery
  • Cloud Top Height
  • Cloud Top Phase
  • Cloud Top Pressure
  • Cloud Top Temperature
  • Derived Motion Winds
  • Aerosol Detection: Smoke and Dust
  • Aerosol Optical Depth
  • Cloud Optical Depth (day/night)
  • Cloud Particle Size Distribution (day/night)
  • Land Surface Temperature (skin)
  • Low Cloud and Fog

System Requirements

  • 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)

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.
