Lightning is a complex atmospheric phenomena having its wide implications in climate sciences and disaster management. To monitor the lightning occurrences over India, NRSC has established a network of long range lightning detection sensors (LDS). These sensors have more than 98% confidence within 300 km range of detection of individual sensors. The network is put in a way to have 50% overlap to enable high geolocation accuracy and maintain redundancy. Time of arrival algorithm is adopted for geolocating the lightning occurrences. The NRSC-LDS network data is indented to generate Atmospheric lighting Essential Climate Variable (ECV) as per the WMO criteria elaborated by the GCOS-2016 report. These ECVs can further be utilized for various atmospheric & climate research and disaster support studies.
