4.1 Analysis of GRACE – GLDAS data sets
The study area is covered with grids pixel 1, pixel 2, pixel 3 and pixel 4 as shown in the figure 2. Both GRACE and GLDAS data sets have spatial resolution of 10×10 pixels. Because of this limitation, the latitude and longitude were separated into single grids by using panoply software 4.10.3. The datasets of GRACE and GLDAS represents different value for different grids and the mid-point of each grid denotes the value of respected data.
