Abstract
NASA GEOS-CCM instantaneous hourly output. Data on a 0.5ºx0.5º resolution. In this dataset, there are 13 meteorological variables used for training the lightning parameterization scheme, SEILER-Net. There is also a Land-Water-Ice flag used for analysis along with the flash rate output from NASA GEOS-CCM that is also used for analysis. Amazon Basin domain (10ºN-22ºS, 35º-67ºW) and USA domain (18º-50ºN, 72º-104ºW) from June 2023-December 2024.
Notes
Data was pre-processed according to SEILER-Net methodology listed in (Seiler, 2026) (in-review). Hours that are included in this dataset are those with at least one grid cell in the domain that has a non-zero flash rate according to corresponding Geostationary Lightning Mapper satellite data. All variables (besides TemperatureLapseRate, MSE ratio, and column relative humidity) were transformed using log base 10 (x+1).
