Add slope/aspect factors for incoming shortwave radiation. Add simple shortwave model for use without data. #48

Closed ecoon closed 3 years ago

As in the title. Especially in the Arctic, slope/aspect variations change the incoming incident shortwave radiation dramatically. It would be good to have a model for:

  1. a factor that multiplied the (data-provided) "flat ground" incoming shortwave, based on slope and aspect and
  2. a simple shortwave model based on latitude, day of year, and other parameters.

Landlab has a simple version of this which looks like it fits the goal here:

Note that realistically a shortwave radiation model is going to need the Julian day. This has showed up in a few ways lately, e.g. leaf on/off for transpiration. Probably need to think of adding this feature to Amanzi or State or as an evaluator.
