Global Water Mass: GRACE Satellite Monthly Data 2002-11
Using an innovative twin-satellite technique to measure the Earth's gravity field, the GRACE project detects changes in water mass without interruption by borders, boundaries, or adverse conditions on the ground. This data set contains GRACE's monthly grids for the span of the mission to date (2002 - 2011). Each cell in the grid shows the water height anomaly for that location compared to its long-term average (in cm of equivalent water height). Each monthly grid comprises 360 x 180 cells, with latitude and longitude tables to geolocate each position.
