[RegCNET] negative evapotranspiration values

[Anna Kis]

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?

I hope someone can help me to deal this problem.

Thank you in advance:
Anna Kis
