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)`
