“…Evaluation of HTSVS by data on mean values of wind speed, temperature, and humidity, and on eddy flux densities (the so‐called eddy fluxes) of momentum, sensible heat, and water vapor gathered during the Great Plains Turbulence Project, GREIV I‐1974 (GREnzschicht Instrumentelle Vermessung phase I, i.e., first phase of probing the atmospheric boundary layer) [e.g., Kramm , 1995], SANA (SANierung der Atmosphäre über den neuen Bundesländer, i.e., recovery of the atmosphere over the new federal countries) [e.g., Spindler et al , 1996], CASES97 (Cooperative Atmosphere Surface Exchange Study 1997) [e.g., LeMone et al , 2000] and BALTEX (BALTic sea EXperiment) [e.g., Raschke et al , 1998] showed that HTSVS accurately simulates the diurnal course of state variables and fluxes [ Kramm , 1995; Mölders , 2000; Narapusetty and Mölders , 2005]. By using lysimeter data from a midlatitude site with occasionally frozen ground in winter Mölders et al [2003a, 2003b] found that HTSVS predicts the long‐term (2050 days) accumulated sums of evapotranspiration and recharge with better than 15% accuracy. Soil temperatures were predicted within 1–2 K accuracy, on average [ Mölders et al , 2003b].…”
