The offline model output routine converts latent heat fluxes to water fluxes as part of the daily/monthly etc, averaging process. This process, however, neglects the difference between evaporation and sublimation in the conversion as captured by the factor ssnow%cls.
Two minor changes to the routine cable_output.F90 are needed:
line 1857: out%Evap = out%Evap + REAL(canopy%fes/ air%rlam/ssnow%cls + canopy%fev/air%rlam,4)
line 1902: out%Esoil = out%Esoil + REAL(canopy%fes/air%rlam/ssnow%cls, 4)
Note the other evaporation outputs do not need to be changed as transpiration (out%Tveg) and evaporation from a wet canopy are assumed to be from liquid water reservoirs.
This conversion should have been applied as part of Ticket 137.
A check is needed to see if a modification of line 1857 is needed to accommodate SLI: Esoil has two cases and Evap is now using the latent heat flux from soil and canopy not the total.
