[gradsusr] Solar Radiation

[Brian Walsh]

Thanks Jeff.

Any idea what parameters I'd need to download and what the formula would look like? Would these parameters be available from the GFS (or similar) model?

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.

Hello,

Are there any models which output the amount of daily solar radiation (whether NWP or reanalysis model)? Or, is there a way of determining this from existing variables?

Thanks in advance.

Brian
