The drought monitor was developed at the Helmholtz Center for Environmental Research (UFZ), which provides daily comprehensive information on the state of soil moisture in Germany. Drought describes the deviation of the soil moisture from the long-term condition in the respective month (statistical comparison with the period 1951-2015), not absolute drought. The soil moisture is calculated depending on the actual soil type over the entire soil horizon (in Germany on average 1.80m thick) and for the top 25cm. The basis are simulations with the mesoscale hydrological model mHM developed at the UFZ.
