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

Calculate Angstrom alpha exponent.

Parameters

  • aod1 (numeric) – first aerosol optical depth

  • lambda1 (numeric) – wavelength in nanometers corresponding to aod1

  • aod2 (numeric) – second aerosol optical depth

  • lambda2 (numeric) – wavelength in nanometers corresponding to aod2

Returns

alpha (numeric) – Angstrom \(\alpha\) exponent for AOD in (lambda1, lambda2)
