Lightning is a natural but destructive phenomenon that affects various locations on the earth’s surface every year. Hence, lightning detection system has been developed and 4-sensors are deployed over North-Eastern Region of India (NERI) with a spatial separation ranging from 105 km to 347 km. A systematic study is carried on calibration and validation of four digital lightning sensors at Regional Meteorological Centre, India Meteorological Department, Guwahati for a period of three months i.e., March, April and May 2011. Simultaneously, the Rain drop Size Distribution (RSD) and rain integral parameters data is obtained from PARSIVEL disdrometer located less than one meter spatial separation. From the preliminary studies on total cloud lightning have found intra and inter-cloud(IC) lightning tend to fluctuate significantly during the lifetime of thunderstorms. The advantage of this study is to support operational meteorological community as prior studies failed to link lightning characteristics to currently used radar interrogation techniques.
