ABX: A Hyperspectral GEO Sounder

An interferometer-based hyperspectral instrument in GEO orbit would provide more frequent, higher-resolution atmospheric soundings than currently available from LEO satellites alone. This can provide information on atmospheric instability before it can be observed with imagery data available today, improving severe weather forecasts while increasing warning times.

This presentation describes the design and performance of the L3Harris ABX instrument, which is a straightforward modification of the existing ABI instruments on GOES R-S. It also shows that the ground processing of ABX data is readily achievable in the commercial Cloud, using simulated ABX data and representative ground processing software.
