The meteorological input fields required for the calculation must be available in hourly resolution and are derived from interpolated weather station data. Furthermore, the model is with Soil information from the soil guide profiles of the soil overview map (BÜK 1000) of the Federal Institute for Geosciences (BGR) and raw materials parameterized. The data have a spatial resolution of 1 x 1 km and cover the whole of Germany. Data outside of Germany are misidentified. All information on the Gauss Krüger projection from the 3rd meridian strip is in the top 6 lines of the file. The raster file can be loaded directly into ArcGis. ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- Origin: The calculations are carried out with the model AMBAV 2.0 (Agrarmeteorologische Berechnung der aktuellen Verdunstung) developed in the Center for Agrometeorological Research (ZAMF) of the DWD. The AMBAV 2.0 model can be operated in a fine grid in 1 x 1 km resolution over Germany in order to achieve better spatial representation. This better spatial representation is further increased by the fact that the typical regional soils are used in the calculation, which were taken from the soil overview map BÜK 1000 of the Federal Institute for Geosciences and Natural Resources (BGR, 2007).
