My research work deals with the study of GPS based Total Electron content (TEC) of Ionosphere and Multisensor parameter related to earthquakes. TEC data can be obtained from dual frequency GPS receiver, which can help to provide a better understanding of the upper atmosphere environment. GPS TEC data have been taken from International GNSS service (IGS) in the RINEX format. Additionally, the analysis of multi-sensor parameters such as SST and SLHF is done using freely available online data. Variation in SLHF, SST and TEC before and after the many earthquakes has been studied in order to find the possible link between land, ocean and ionosphere prior to earthquakes.
