Atmospheric lightning is an outcome of interplay among the meteorological parameters under the influence of convective processes occurring in troposphere. Radiation, temperature and wind are the prime driving parameters of the convective phenomena. Often, the reanalysis data has been utilized to understand the precursor of the lightning occurrences. As the lightning is a disaster where nowcasting is important, for operational utilization, it is deemed to utilize space-borne near real-time measurements. The present study investigates the utilization of existing near real-time Indian remote sensing Satellite data to identify the signatures of of the lightning occurrences. Results reveal a lead-time of about 2.5 hours can be achieved when these precursors are used for lightning occurrences. The study provides first step into the prediction of the lightning occurrences over India using the Indian remote sensing geostationary satellite.
