Gridded GLM Software Package V1.0 Release

Post by kathys »

Dear Colleagues,

The CSPP Geo Team is pleased to announce that the Gridded Geostationary Lightning Mapper (Gridded GLM) software package 1.0 is now available for download.

Capabilities

The software is capable of processing GOES-16, GOES-17 and GOES-18 GLM Level 2+ products in mission standard format, generating a new set of products that 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 following products can be produced:
- Minimum Flash Area
- Flash Extent Density
- Total Optical Energy

Products are compatible with the Satpy Python library, and with display packages that are built with Satpy such as Geo2Grid. AWIPS-compatible tiles can optionally be generated, using functionality that was developed within the open source Python SatPy library.

Input GLM L2+ files can be obtained from the CSPP Geo GRB software running at a direct broadcast site, or from NOAA CLASS. Output is in NetCDF4 format.

History and Attribution

The software package is built on the open source glmtools software developed by Dr. Eric Bruning (Texas Tech University). Ongoing development of operational Gridded GLM products and related research is led by Dr. Scott Rudlosky (NOAA/NESDIS/STAR). This release builds on 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.

Bruning, E. C., Tillier, C. E., Edgington, S. F., Rudlosky, S. D., Zajic, J. K., Gravelle, C. M., Foster, M., Calhoun, K. M., Campbell, P. A., Stano, G. T., Schultz, C. J., and Meyer, T. C. (2019). Meteorological imagery for the Geostationary Lightning Mapper. 2019: Meteorological imagery for the Geostationary Lightning Mapper. J. Geophys. Res., 124 (24), 14 285–14 309, doi:10.1029/2019JD030874

The CSPP Geo package was developed at the University of Wisconsin - Madison, SSEC / CIMSS, under funding provided by the GOES-R Program and NOAA STAR. The lead developers are Nick Bearson and Dave Hoese. Assistance with tiling and AWIPS-compatibility was provided by Lee Byerle and Joe Zajic from the National Weather Service TOWR-S team.

System Compatibility

The software runs on CentOS7-compatible Linux, and was successfully tested on an 8-core Intel Xeon E-2278G system with 32GB RAM, running on a live GRB data stream along with the GRB software package.

Software Download and Installation

The version 1.0 software and a test data tarball can be obtained from the CSPP Geo website (free registration required). Basic instructions, usage examples and links to product documentation can be found in a very useful README file in the program tarball. The software package is self-contained; installation of additional third-party software is not required.

Best regards,

Scott Lindstrom for the CSPP Geo Gridded GLM developers and Managers
