LIS/OTD 2.5 Degree Low Resolution Diurnal Climatology (LRDC)

Gridded OTD+LIS combined product - 2.5 deg. diurnal flash rate climatology

Combined OTD (Optical Transient Detector) + LIS (Lightning Imaging Sensor) total (interclouds+cloud t0 ground) flash production gridded to 2.5x2.5 lat/lon. is given as a daily climatology. The time span is 5 yrs of the satellite mission (OTD 4/95-3/00, LIS 1/98-12/02). The climatology is determined as the total number of flashes at a given location over the total viewing time of the sensor. In addition, the resulting flash production is weighted by the instrument detection efficiency. The data are calculated as hourly diurnal climatology.
If the data are used please cite :
"The v1.0 gridded satellite lightning data were produced by the NASA LIS/OTD Science Team (Principal Investigator, Dr. Hugh J. Christian, NASA / Marshall Space Flight Center) and are available from the Global Hydrology Resource Center (http://ghrc.msfc.nasa.gov)."
