Re: CCSM3 moisture flux divergence

Mike,

I did this long time ago using CAM3.0. If I remember correctly,
adding the following four lines in "diagnostics.F90" do the trick:

Line 118: call addfld ('UQ ','m/skg/kg',pver, 'A','Zonal water
transport',phys_decomp)
Line 173: call add_default ('UQ ', 1, ' ')
Line 480: ftem(:ncol, = state%u(:ncol,*state%q(:ncol,:,1)
Line 481: call outfld ('UQ ',ftem ,pcols ,lchnk )

Of course, you need to add "UQ" to the FINCL1 list.
