dc.description.abstractGRACE mission is a joint venture of NASA and GFZ. This mission was launched to provide with unprecedented accuracy, estimates of the global high resolution models of the Earth's gravity field. The study of time-variability of Earth's gravity field is very helpful in climate sciences and earth's sciences studies. People have done a lot of work to demonstrate the effect of many natural activities on gravity. Gravity estimates from GRACE is an important tool for estimating mass redistribution at continental scale whether we talk about hydrology, seismology or glaciology. GRACE is a potential tool to observe many phenomenon and still we can see a lot of things which we need to explore. This research work focuses on hydrological events such as floods and drought, seismic events such as earthquakes and volcanic activity and at last the glacier melting trend anal-ysis. The work includes the development of strategy of analysis for these events keeping in mind their behaviour and GRACE limitations of spatial resolution and sensitivity. Further in this work we would produce a event calendar for such events stating whether gravity changes imparted by such events are visible to GRACE.We would look at different hydrologi-cal, seismological and glacier melting events occurred in the life time of GRACE satellites while generating the calendar. Calendars are generated for hydrological events, floods and droughts separately and also for earthquake events. For rest of the phenomenon we have not generated calendars since these events are very few in numbers. This work is qualitative analysis so we could observe whether GRACE signal is able to observe these events or not. We have given the possible explanation for the events not visible, and those visible have helped in the development of a methodology for analysis of a particular event.The work finally produces a series of events which were able to observe by GRACE and we also get the methodology suitable for analysis of an eventen_US
