Hourly Gridded Accumulations of Geostationary Lightning Mapper (GLM) Flash Counts on the NCEP G211 Grid (2018–2026)

This dataset provides a continuous, high-resolution record of lightning activity across the Americas and adjacent oceanic regions, derived from the Geostationary Lightning Mapper (GLM) instruments aboard the GOES-16 and GOES-19 satellites. Lightning flash counts are accumulated hourly onto the NCEP G211 (approximately 40 km) and a nested 20 km half-spacing grid for the period January 2018 through December 2026. The data are provided in netCDF-4, adhering to CF-1.8 metadata conventions. This collection is designed to support the training and validation of machine learning models. By standardizing diverse satellite eras into a uniform spatial and temporal framework, this dataset lowers the barrier for multi-year lightning climatology research.
