[gradsusr] Solar Radiation

[Jeff Duda]

Hey Brian,
I bet you could estimate radiation as a residual from the thermodynamic
equation.  You could estimate the local change, the advection, the
molecular diffusion, and the latent heating from water phase changes which
only leaves radiation as the other major term (making assumptions about the
scale of the features you are examining, of course).  Then combine those
and assume that whatever is left over is due to radiation.  Then I think
you would multiply by air_density*Cp to get a radiation value in W/m^2.
