It appears that the science basis of CABLE's longwave radiation at the soil assumes an emissivity of 1 but we still permit emissivity \=1 in the emitted radiation.
This is unphysical (the met%fld term should have an C%EMSOIL term multiplying it).
Energy conservation would not be possible in ACCESS if soil emissivity were not 1.
A trivial fix is not possible as this needs to interface properly with the canopy radiation exchange.

| by inh599It appears that the science basis of CABLE's longwave radiation at the soil assumes an emissivity of 1 but we still permit emissivity \=1 in the emitted radiation.
For example
canopy%fns = rad%qssabs + rad%transdmet%fld + (1.0-rad%transd)C%EMLEAF & C%SBOLTZcanopy%tv*4 - C%EMSOILC%SBOLTZ* tss4
in cable_canopy
