GLDAS Noah Land Surface Model
Global Land Data Assimilation System, version 2.1. Modelled ET, soil moisture, runoff and snow.
Noah land surface model output forced by a mix of reanalysis and observation-based data, giving a consistent set of water balance terms: evapotranspiration, surface and subsurface runoff, soil moisture in four layers and snow water equivalent. GLDAS-2.0 extends back to 1948.
