cloud_cover_to_transmittance_linear
(cloud_cover, offset=0.75, **kwargs)¶ Convert cloud cover (percentage) to atmospheric transmittance using a linear model.
0% cloud cover returns “offset”.
100% cloud cover returns 0.
- Parameters
cloud_cover (numeric) – Cloud cover in %.
offset (numeric, default 0.75) – Determines the maximum transmittance. [unitless]
kwargs – Not used.
- Returns
transmittance (numeric) – The fraction of extraterrestrial irradiance that reaches the ground. [unitless]
