Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) gridded land characteristics

The VEMAP Reference Data collection contains the following datasets:

Geography - elevation, area, and percent land area for each VEMAP grid-cell. Landcover - potential natural vegetation under current conditions. Soil modes - the number of dominant (modal) soils in each VEMAP grid-cell for which soils data are available.

Note that the VEMAP1 published simulations were based on the mineral soil component for modal soil 1.

Soils (mineral, organic, and total) - up to 18 variables that make up the mineral or organic component of the soil, or combined for a total soil value. Variables are available for each modal soil (1-4) and for an average soil. Many variables are available for an upper (0-50 cm) and lower (50 -150 cm) soil layer.

Data provided by the Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) at the National Center for Atmospheric Research (NCAR) are gridded monthly time series climate data for the Conterminous United States at 0.5 x 0.5 degree spatial resolution.
