pvlib.forecast.HRRR_ESRL.cloud_cover_to_irradiance_clearsky_scaling#

HRRR_ESRL.cloud_cover_to_irradiance_clearsky_scaling(cloud_cover, method='linear', **kwargs)#

Estimates irradiance from cloud cover in the following steps:

  1. Determine clear sky GHI using Ineichen model and climatological turbidity.

  2. Estimate cloudy sky GHI using a function of cloud_cover e.g. cloud_cover_to_ghi_linear()

  3. Estimate cloudy sky DNI using the DISC model.

  4. Calculate DHI from DNI and GHI.

Parameters

  • cloud_cover (Series) – Cloud cover in %.

  • method (str, default 'linear') – Method for converting cloud cover to GHI. ‘linear’ is currently the only option.

  • **kwargs – Passed to the method that does the conversion

Returns

irrads (DataFrame) – Estimated GHI, DNI, and DHI.
