 This study compared actual evapotranspiration, ETA, measurements by a set of six-wayable lysimeters, ETA estimates obtained with the eddy covariance, EC, method, and evapotranspiration calculated with the Penman-Montieth equation, ETPM, for the Rolls-Brösch site in the Eiffel, western Germany. The comparison of ETA measured by EC, including correction of the energy balance deficit, and by lysimeters is rare in the literature and provides insight into the performance of both methods. An evaluation of ETA for the two methods for the year 2012 shows a good agreement with a total difference of 3.8 percent, 19 millimeters, between the ETA estimates. The highest agreement and smallest relative differences, less than 8 percent, on a monthly basis between both methods are found in summer. ETA was close to ETPM, indicating that ET was energy limited and not limited by water availability. ETA differences between lysimeter and EC were mainly related to differences in grass height caused by harvest and the EC footprint. The lysimeter data were also used to estimate.
