CSPP Geo Gridded GLM Software Version 1.0b1 Released

CSPP Geo Gridded GLM Software Version 1.0b1 Released

Postby jbraun » Thu Mar 11, 2021 4:09 pm

Dear Colleagues,

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

Capabilities

The software is capable of processing GOES-16 and GOES-17 GLM Level 2+ 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 following products can be produced:
- Minimum Flash Area
- Flash Extent Density
- Total Optical Energy

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.

Note that beta software has not been as thoroughly tested as a typical production release. Additionally there may be changes affecting functionality and interfaces before the Version 1 production release.

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 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.

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 beta 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 README file in the program tarball. The software package is self-contained; installation of additional third-party software is not required.

Contact

We welcome feedback from users on this beta software and the products, as well as any future improvements people would like to see. Please direct any feedback or questions to csppgeo.issues@ssec.wisc.edu.
