Long-term map of where lightning strikes most
What it measures. A long-term map of how often lightning strikes around the world, given as flash rates on a half-degree grid.
How it's made. Combines years of lightning detections from two space sensors, the Optical Transient Detector on OrbView-1 and the Lightning Imaging Sensor on the TRMM satellite, merged into one climatology.
How & where you'd use it. Useful for understanding where thunderstorms are most common, for climate studies, and for fields like aviation and power-grid planning that care about lightning risk.

Official description
The LIS/OTD 0.5 Degree High Resolution Full Climatology (HRFC) contains a variety of gridded climatologies of total lightning flash rates obtained from two lightning detection sensors - the spaceborne Optical Transient Detector (OTD) on Orbview-1 and the Lightning Imaging Sensor (LIS) onboard the Tropical Rainfall Measuring Mission (TRMM) satellite.The long LIS (equatorward of about 38 degree) record makes the merged climatology most robust in the tropics and subtropics, while the high latitude data is entirely from OTD. The HRFC dataset include flash rate climatology data including raw and scaled flash on a 0.5 degree grid in HDF and netCDF-4 format.
