[MITgcm-support] strange hflux value in MON exf_hflux

[Chun-Yan Zhou]

Hi, there,
I use hflux in data.exf, with the max and min 679 and -247,
however, the exf_hflux_max in the output is 1200, which is much more than the biggest number in the file I provide. Besides, I did not provide the sflux file, the exf_sflux_max still had value.
                                      MON exf_hflux_max                =   1.2212290649558E+03
(PID.TID 0000.0001) %MON exf_hflux_min                =   2.7547387234863E+00
(PID.TID 0000.0001) %MON exf_hflux_mean               =   5.1822075200978E+02
(PID.TID 0000.0001) %MON exf_hflux_sd                 =   3.0564424766070E+02
(PID.TID 0000.0001) %MON exf_hflux_del2               =   5.4699216688885E-02
(PID.TID 0000.0001) %MON exf_sflux_max                =   3.2260977333231E-07
(PID.TID 0000.0001) %MON exf_sflux_min                =   1.0412672397707E-09
(PID.TID 0000.0001) %MON exf_sflux_mean               =   1.3920299907157E-07
(PID.TID 0000.0001) %MON exf_sflux_sd                 =   7.6904666535711E-08
(PID.TID 0000.0001) %MON exf_sflux_del2               =   1.5054136398581E-11
Maybe there is another factor contributing the exf_hflux_ma?
Any help is much appreciated.
