Measurements of evapotranspiration using a dynamic lysimeter

Johnson, Torbjörn; Odin, Hans


A new dynamic weighing lysimeter is described. Digital values of evapotranspiration, condensation or wet fog deposition are summed up during 1-2 minutes and are recorded automatically. The evapotranspiration from lichens and heather vegetation measured by means of the lysimeter and that calculated by the Bowen ratio energy balance method are compared. Some errors in evaluation of evapotranspiration by means of both methods are discussed.
