LIS/OTD 0.5 Degree High Resolution Monthly Climatology (HRMC) V2.3.2015

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Catalog Last Checked: July 14, 2026 at 10:30 PM | Dataset Last Updated: June 23, 2026
The LIS/OTD 0.5 Degree High Resolution Monthly Climatology (HRMC) 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 HRMC dataset include monthly flash rate climatology and flash rate seasonal climatology data on a 0.5 degree grid in HDF and netCDF-4 format.
