Dear CAM-users,
I have the following problem, if any body can give me suggestion in this regards will be of great help.

PROBLEM = The global average time mean total surface reaching precipitation is not equal to the global average time mean surface evaporation.

METHOD = Time average has been tested for 1 years, also I checked upto 10 years.
Total surface reaching precipitation is calculated by using "PRECT"
Total surface evaporation is calculated by using "LHFLX"

MAGNITUDE OF MIS-MATCH = upto 7% to 8% of global average precipitation(as shown in the figure).

I have checked the above for all the three dynamical core(EUL, SLD, FV) of CAM3 and found the similar miss-match.

QUESTION = Why is the mis-match ?

Thanks in advance,
Saroj
