CSPP Geo Gridded GLM software processes GOES-16 and GOES-17 Geostationary Lightning Mapper (GLM) Level 2+ LCFA products in mission standard format, generating a new set of products which have been gridded to the Advanced Baseline Imager (ABI) 2-km resolution, and are aggregated at one-minute intervals. Spatial extent information that is not readily available in the GLM L2+ data is recovered and used to create the gridded products.

## OVERVIEW
CSPP Geo Gridded GLM software processes GOES-16, -17, -18 and -19 Geostationary Lightning Mapper (GLM) Level 2+ LCFA products in mission standard format, generating a new set of products which have been gridded to the Advanced Baseline Imager (ABI) 2-km resolution, and are aggregated at one-minute intervals. Spatial extent information that is not readily available in the GLM L2+ data is recovered and used to create the gridded products.
The new gridded products are:

This release builds on two years of effort to refine the glmtools package in pre-operational demonstrations, and many of the contributors to that effort are coauthors on the paper that describes the GLM imagery creation approach in detail.
