Assessment of Evapotranspiration in Ecosystems
Original language description
This paper deals with the online and offline assessment of evapotranspiration using mathematical models instead of direct measurement. The evapotranspiration was estimated using the Penman-Monteith Method and the Bowen Ratio Method on data obtained from14 ground meteorological stations deployed around the landscape of South Bohemia in the Třeboň region. These data were recorded in 10-minute intervals and transferred via the GPRSS network to a server where they were accessed through Internet. Several times a year, these data were complemented by infrared images captured by aerial photography. The thermographic screening was done with an airship and by an aircraft for different altitudes. These infrared images helped to improve the evapotranspiration estimate in the vicinity of the meteorological stations. The data processing and modeling of the evapotranspiration of the selected ecosystem was done using the Matlab programming environment and its toolboxes. This paper also describes the
