Abstract

This resource holds the MERRA Spatial Downscaling for Hydrology (MSDH) downscaling tool developed to provide sub-daily high spatial resolution surfaces of weather variables for distributed hydrologic modeling from NASA Modern Era Retrospective-Analysis for Research and Applications reanalysis products. The tool uses spatial interpolation and physically based relationships between the weather variables and elevation to provide inputs at the scale of a gridded hydrologic model, typically smaller (∼100 m) than the scale of weather reanalysis data (∼20–200 km).

Detailed information on and an evaluation of MSDH is given in Sen Gupta, A. and D. G. Tarboton, (2016), "A tool for downscaling weather data from large-grid reanalysis products to finer spatial scales for distributed hydrological applications," Environmental Modelling & Software, 84: 50-69, http://dx.doi.org/10.1016/j.envsoft.2016.06.014.
