#### 3.2.2 Sensible Heat Flux (SHF)  
Even if the number of days in which it is possible to evaluate a daily mean is limited (sonic anemometer was only installed during the vegetative season), analyzing the statistical values reported into Tables 5-7, and looking at Supplementary Figures S2-S4, S25 and S26, it is evident that the simulations tend to amplify the range with respect to observed values, showing some negative values, especially when GLDAS-2.0,2.1 is used and the vegetation is irrigated crop. In more detail, EXP1a shows mean and median values closer to observations (about 2-20 W m\({}^{-2}\) of difference) than EXP2a (\(\sim\)9-23 W m\({}^{-2}\) of difference) and EXP3a (difference: \(\sim\)22-28 W m\({}^{-2}\)) in all stations, due to the maxima being too low in EXP2a and in EXP3a, while EXP1b shows larger mean values (\(\sim\)28-50 W m\({}^{-2}\) of difference). EXP2b values (difference: \(\sim\)2-10 W m\({}^{-2}\)) seem more similar to the observations than EXP3b ones (difference: \(\sim\)10-16 W m\({}^{-2}\)), but all \"b\" experiments show extremes too large (in absolute value), with quite negative values in EXP2b and EXP3b, thus producing ranges even four times bigger than the observations (as for EXP2b in FB). Thus, in the case of sensible heat flux (SHF), the use of vineyards as vegetation type appears fundamental in getting the best results, and the use of GLDAS-2.0,2.1 data as boundary conditions slightly deteriorates the quality of the outputs, even if the differences, on daily basis, remain approximately in the range 20-30 W m\({}^{-2}\), value that could also be considered as the typical uncertainty of measurements with sonic anemometers [53; 54].
