GRACE and GRACE Follow On: On Accurate estimation of Groundwater Storage Change from Satellite Gravimetry and Beyond

Several GRACE downscaling products already available for regional analysis owing to its coarse resolution (~3°). But they lack validation (both original GRACE and downscaled product). Here for the first time, we have validated both, Original GRACE and downscaled product. Along with developed a new product which is outperforming the existing products over most of the parts of India. Thereby, we are offering a valuable tool for regional water resource analysis.
