I have a quick look: Any thoughts?? Both are still in the SCM option.

/scratch/w40/qh5472/cylc-run/u-cy071/share/fcm_make/extract/um/src/atmosphere/convection/conv_surf_flux.F90

```
flux_e(row_length,rows) & ! Specified surface
! latent heat flux (W/m^2)
flux_h(row_length,rows) & ! Specified surface
! sensible heat fluxes (in W/m2)
tstar(row_length,rows) & ! Surface temperature
! (= top soil layer temperature) (K).
```
