Hi Fred, re: > I would like to generate a convective product for GOES-16, and would > like to overlay the GOES-16 GLM lightning data. Sounds interesting. re: > Does Unidata have GLM lightning data which is accessible via ADDE? I just setup three GLM datasets on lead.unidata.ucar.edu as type POINT (as per instructions in the McIDAS v2017 DSSERVE HELP): RTGOESR/GLMEVENT RTGOESR/GLMFLASH RTGOESR/GLMGROUP I have not tried doing anything with this dataset yet, so I will not be able to answer many, if any, questions on how to use them. HELP DSSERVE shows the following for GLM data: You can access GOES-R Series (GOES-16 and later) netCDF Geostationary Lightning Mapper (GLM) point files with the GLMDISP, GLMLIST and PT* commands by using DSSERVE to assign a dataset name to the files. When doing so, specify "GLMN" in the 'format' parameter, TYPE=POINT, the directory and file masks to the netCDF point files in the DIRFILE keyword, and the configuration file that maps the netCDF file parameter names to McIDAS parameter names in the INFO keyword. Three configuration files for GLM data are provided in the ~mcidas/data directory: GLM_EVENT.cfg, GLM_FLASH.cfg and GLM_GROUP.cfg.
