ALDIS cloud to ground lightning strike occurrence aggregated to spatiotemporal ERA5 cells (summer months 2010 to 2019)

The dataset contains a binary classification whether at least one cloud-to-ground lightning flash as detected by the ALDIS [1] lightning location system occurred in the previous hour in an ERA5 grid cell. Data with an amplitude between -2 kA and +15 kA are excluded. The data cover 8.25E to 16.75E longitude and 45.25N to 49.75N latitude.Non-commercial use is allowed conditional on proper citation of the data source, ALDIS, and the accompanying manuscript Ehrensperger, G., Simon, T., Mayr, G.
