Model input
To run STEP-TRAMM you need maps of elevation and landcover, and information on rainfall event and soil properties. We propose to use the following publicibly available data bases to obtain this information:
Elevation map
Digital elevation data from external page SRTM with 30 m resolution can be downloaded. You need an account on external page earthexplorer.
Forest map
Global forest maps and deforestation with resolution of 30 m can be external page downloaded from University of Maryland.
Rainfall
Global rainfall information over several years can be found in external page CMORPH data base (with temporal resolution of 3 hours and 0.25 degrees spatial resolution)
Soil type
The external page SoilGrids data base provides soil information with spatial resolution of 250 m. STEP-TRAMM needs the soil textural class for a specific site that can be deduced from sand, silt and clay fraction.
