Daily grids of soil moisture under winterwheat for Germany
The daily grids of soil moisture are calculated for 10 cm layers up to a depth of 2 meters for selected agricultural crops with the AMBAV 2.0 model. The meteorological input fields required for the calculation must be available in hourly resolution and derived from interpolated weather station data. Furthermore, the model is parameterized with soil information from the soil guide profiles of the Bodenübersichtskarte (BÜK 1000) of the Federal Institute for Geosciences and Natural Resources (Geowissenschaftenund Rohstoffe, BGR).
The data have a spatial resolution of 1 x 1 km and cover the whole of Germany. Data outside of Germany are considered as missing values.

- Specific usage
-
The input fields, which have to be available in hourly resolution and were generated from station data via interpolation, cannot accurately reflect the actual conditions on site, so that depending on the weather situation, differently large deviations from reality can arise. This is especially true for the small-scale, strongly varying precipitation. Even if the model approach has been validated with known model input variables over years and different weather situations, it is not able to reproduce reality 100% because the simulated processes are very complex and can only be described by approximations. Not all of the assumed soils could be accurately tested.

The soil moisture values are specified in percentage of usable field capacity. In order to calculate the volumetric water content from these values, the grid files for field capacity (AG_SOILINFO_THETAFC.nc) and wilting point (AG_SOILINFO_THETAWP.nc) can be used.
The volumetric water content can be calculated by:
Theta = PAW * (FC - WP) / 100 + WP
Theta = Volumetric water content
PAW = Soil moisture values in percentage of usable field capacity
FC = Field capacity
WP = Wilting point

The calculations are carried out with the model AMBAV 2.0 (Agrarmeteorologische Berechnung der aktuellen Verdunstung) developed in the Zentrum für Agrarmeteorologische Forschung (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 Bundesanstalt für Geowissenschaften und Rohstoffe (BGR, 2007).
More detailed information can be found in Herbst et al. 2021.
