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 and for predefined layer thicknesses of 0-30, 0-60 and 0-90 cm for three different agricultural crops using the AMBAV 2.0 V1.5 model. The meteorological data required for the calculation input fields must be in hourly resolution and are provided by interpolated weather station data. Furthermore, the model with soil information from the soil guide profiles of the usage-differentiated soil overview map (BÜK 1000 N) parameterized by the Federal Institute for Geosciences and Natural Resources (BGR). If the type of soil is the same, the soils differ depending on their use. In addition, the depth of the soil and the skeletal content (coarse soil > 2 mm) in the various soil layers are taken into account.
The data has a spatial resolution of 1 x 1 km and is completely comprehensive Germany from. Data outside of Germany or in settlement areas with sealed areas have an incorrect identifier -9999. All information about the grid is stored in the metadata of the netcdf file.

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 Viewer displays the soil moisture and other water balance variables that allow the water supply in the soil to be monitored. This enables an initial assessment of the situation, e.g. during periods of heavy rainfall, aridity, and drought.

- Statement
-
The calculations are carried out using the model developed at the DWD's Centre for Agrometeorological Research (ZAMF), AMBAV 2.0 (Agrometeorological Calculation of Current Evaporation) version 1.5. The AMBAV 2.0 model can be operated in a fine grid with a resolution of 1 x 1 km over Germany in order to achieve better spatial representation.
This improved spatial representation is further enhanced by the fact that the typical regional soils used in the calculation are taken from the soil overview map BÜK 1000N of the Federal Institute for Geosciences and Natural Resources (BGR) (BGR, 2007). More detailed information can be found in Herbst et al. 2021.
