CAM5 - RRTMG - archiving upwelling/downwelling SW/LW flux at each model levels

[amatcaos@caos_iisc_ernet_in]

Hello,
I am using CAM5 with RRTMG radiation package.I wanted the upward/downward shortwave (SW) and longwave (LW) fluxes at each model levels (30 model levels). There are no output SW/LW flux defined variables.Is it possible to output the upwelling and downwelling SW/LW fluxes at all 30 model mid levels? basically, I need them to calculate the net radiative fluxes at each model levels. At model top I have FSNT, FLNT. So, similar variables I need for each model level.Many ThanksAngshuman

This can't be done without code modifications.  If you look in rrtmg/radiation.F90 the radiation_tend subroutine has calls to rad_rrtmg_sw(.., su, sd, ...) and rad_rrtmg_lw(.., lu, ld).  The variables su, sd, lu, and ld contain the information you're looking for except that it is spectrally resolved, and I believe the fluxes are at layer interfaces rather than midpoints.
