a) dynamically downscaled data
b)statistically downscaled data
a) temperature based variables and indices, radiation, water balance, atmospheric and pressure levels related variables, 2D and 3D,
- 50 and 15 km resolution
b) Climate variables; hydrologic projections
Resolution - approx. 6km for Columbia, upper Missouri, and upper Colorado basins and approx. 12km for the Great and lower Colorado basins
