Global shortwave calculation on cloudy days #6

Open MoonRaker opened 8 years ago

MoonRaker commented 8 years ago

The values that are used to calculate total shortwave radiation, ghi, is not as accurate on overcast days.

An alternative would to use lookup tables of known values of radiation for certain cloud types or to find a simple global shortwave radiation model for cloudy days.

This is relevant only to the Liu & Jordan radiation models that have been added to irradiance.py. Some testing will be necessary to see how necessary an alternative is.
