NDFD.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]
