Turning on absorbed PAR for shaded and sunlit canopy in CLM 5 (Satellite Phenology)

Is it possible to turn on PARSHA and PARSUN while running CLM 5.0 in satellite phenology mode?

Some updates:

 

The absorbed PAR for sunlit and shaded leaves are calculated in SurfaceRadiationMod.F90 (though Photosynthesis.F90 and CanopyStateType.F90, and SolarAbsorbedType.F90 also seem to call them). I tried to add these two variables as history fields in that code. The only time I got it to work is when I directly added the parsun_z_patch (parsha_z_patch) variable as outputs, though CLM gave missing values for the entire world when I did that. 

Ideally, I would want the total absorbed PAR for sunlit canopy for all the canopies, something like:

        parsun(p) = 0._r8

        parsha(p) = 0._r8

        do iv = 1, nrad(p)

           parsun_z(p,iv) = forc_solad(g,ipar)*fabd_sun_z(p,iv) + forc_solai(g,ipar)*fabi_sun_z(p,iv)

           parsha_z(p,iv) = forc_solad(g,ipar)*fabd_sha_z(p,iv) + forc_solai(g,ipar)*fabi_sha_z(p,iv)

           parsun(p) = parsun(p) + parsun_z(p,iv) 

           parsha(p) = parsha(p) + parsha_z(p,iv) 

        end do

 

However, I have not been able to get parsha and parsun as outputs. Every time I compiled the code, I got versions of these errors:

This name has not been declared as an array or a function.   [PARSUN]

This name has not been declared as an array or a function.   [PARSHA]

 

I have declared parsun and parsha where the other variables are declared, so I am unsure of what I am doing wrong. 

I am attaching my modified SurfaceRadiationMod.F90

I think you need to put your pointer declarations in SolarAbsorbedType.F90, since you are referencing solarabs_inst
