| Forcing | Downscaled NLDAS-2 |
Downscaled NLDAS-2 forcing is downscaled to the WLDAS grid using a slope and aspect correction for radiation data and a standard atmospheric lapse rate correction (6.5 K/km) according to topography for all other fields (surface temperature, surface pressure, downward longwave radiation, and relative humidity). Precipitation data are spatially downscaled using the 800 m Parameter-Elevation Regressions on Independent Slopes Model (PRISM) monthly climatology of precipitation.
