We have ran RegCM4 at the Dept. of Meteorology, Eötvös Loránd University. The model version is RegCM-4.3-rc15_cordex_noirrigation (RegCM-4.3-rc15_cordex_noirrigation_bf_ha.tar.gz - that is what we downloaded).

Now I work with SRF files and I have found negative Total evapotranspiration (evp) values. I was wondering how should I interpret these negative values? Furthermore, the unit is "kgm-2day-1" and the time step is 6 hours - so if I would like to get an evapotranspiration value for 1 day, should I divide by 4 the values and then make a daily sum?
