pvlib.atmosphere.angstrom_alpha(aod1, lambda1, aod2, lambda2)[source]#

Calculate Angstrom alpha exponent.

Parameters

  • aod1 (numeric) – Aerosol optical depth at wavelength lambda1. [unitless]

  • lambda1 (numeric) – Wavelength corresponding to aod1. [nm]

  • aod2 (numeric) – Aerosol optical depth at wavelength lambda2. [unitless]

  • lambda2 (numeric) – Wavelength corresponding to aod2. [nm]

Returns

alpha (numeric) – Angstrom \(\alpha\) exponent for wavelength in (lambda1, lambda2). [unitless]
