Description

The GLM Events and Flashes Data consist of the size and number of lightning flashes and events. The data were collected from the Geostationary Lightning Mapper (GLM) instrument on the GOES-16 and GOES-17 satellites and are available as L1b events (raw) and L2 flashes (processed). They are available from March 15, 2021, through March 18, 2021, in netCDF-4 and HDF-5 formats.
