Hi Shani, You can use the variable SWE_inst ("snow depth water equivalent") from GLDAS NOAH 2.0. You can see a list of GLDAS outputs in the README file for the GLDAS data products, which can be found on each of our GLDAS data collection landing pages at GES DISC, e.g. here: https://disc.gs...

Hi Gaurav, I am not sure that using runoff as a proxy for river and lake storage is a good strategy. In the GLDAS models, runoff, along with precipitation and evapotranspiration, is a flux out of (or into) a grid cell. To calculate groundwater storage change (dGW), you are using an equation like thi...

Hi Gaurav, Like Andrew said, surface water might mean different things in different contexts. In the context of the paper you linked, surface water (storage) is defined as the residual in the water balance equation (Equation 2 in the paper) when you subtract groundwater storage, soil moisture, and s...
