I have found an equation in an article which will give me the spectral irradiance due to sunlight as function of longitude, latitude, atmospheric pressure, surface albedo, and precipitable water vapor.
I haven't really worked with these sorts of problems before, so my question is how to turn spectral irradiance into heat flux--in other words, to convert W/m^3 to W/m^2. I'm thinking the best thing to do would be to integrate the function with respect to wavelength, and plug in the max and min wavelengths of interest. But what would those be for sunlight?
also, if anyone can think of a simpler way to model heat flux due to solar radiation as a function of time, I'd be interested in hearing it. the equation in this paper is extremely complex and i don't need anything too accurate--as long as its within a degree or two it will serve my purposes just fine.
thanks
