[MITgcm-support] Relative Humidity

[Martin Losch]

Hi Ankur,

I am returning this to the support list, as your experience may be interesting to others as well.

I, too, are getting out of range values for heat fluxes with CORE, but I usually do not worry about them (just set exfCheckRange=.false.). Maybe it is worth looking into that? It might be a good idea to modify the routine exf_check_range.F (remove the stop statement) and call it at every time step (from exf_getforcing.F) in order to see, if these extremes appear all the time or just at the begining of the intergraion.

The reason they are negative at some places is that they are substracting a zonally average number at each grid point to correct the data towards observed heat fluxes. I am also setting them to zero for my simulations hoping that it doesn't affect the heat balance.
