    6666Following plots are the mean diurnal cycle over the last 40 days of the runs

     71Checking CABLE fluxes in more detail pointed to inconsistencies in the emissivity. cable_data.F09 has
     72{{{
     73     emleaf = 1.0, & ! leaf emissivity
     74     emsoil = 1.0, & ! soil emissivity
     75}}}
     76but rad_ctl.F90 has code that uses the input emissivities
     77{{{
     78       ! Types match tiles here.
     79        emis_tiles(1:npft) = emis_pft
     80        emis_tiles(npft+1:ntype) = emis_nvg
     81}}}
     82
     83At the moment these are still set to the JULES values in the model configuration with only a change for the number of PFTs.
     84{{{
     85emis_nvg_io=9.70000e-1,9.85000e-1,9.00000e-1,9.90000e-1
     86emis_pft_io=13*0.9800
     87}}}

     89Setting all these to 1 in the SCM tests gives a much better energy balance.

     100However now there's almost no difference between the CABLE radnet_tile and the grid box net radiation, showing that CABLE isn't updating it for the change in surface temperature. Correction in {{{cable_soilsnow}}} is controlled by
     101{{{
     102      IF (cable_user%L_REV_CORR) THEN
     103}}}
