Estimates of monthly average water storage in different components of the water cycle for 2003-2012 at 1⁰. Estimates were derived by assimilating satellite data into a model ensemble. Data are available for sub-surface (soil and groundwater) storage and storage in ice & snow, rivers, lakes, and oceans.
