Agricultural Drought monitoring system

In the ADMS, meteorological conditions that are causing drought are evaluated by the climatic water balance (CWB). The CWB expresses the difference between the precipitation and potential evapotranspiration. Atmospheric precipitation is measured at meteorological stations, while the value of potential evapotranspiration (approximating the capacity of the evaporation of water from living short grass) is calculated using the Penman method. This value can also be determined with a high precision using simplified formulas, which include meteorological elements that are normally measured at the meteorological stations of the Institute of Meteorology and Water Management (IMGW-PIB).
