- LW time-step adjustment:
- adjust sfc downward LW flux to account for t changes in the lowest model layer. compute 4th power of the ratio of
tf
in the lowest model layer over the mean value tsflw
.
- normalize by average value over radiation period for daytime.
- adjust sfc net and downward SW fluxes for zenith angle changes.
- adjust SW heating rates with zenith angle change and add with LW heating to temperature tendency.
