pvlib.atmosphere.angstrom_aod_at_lambda(aod0, lambda0, alpha, lambda1=700.0)

Get AOD at specified wavelength using Angstrom turbidity model.

Parameters:

aod0 : numeric

aerosol optical depth (AOD) measured at known wavelength

lambda0 : numeric

wavelength in nanometers corresponding to aod0

alpha : numeric

Angstrom \(\alpha\) exponent corresponding to aod0

lambda1 : numeric, default 700

desired wavelength in nanometers

Returns:

aod1 : numeric

AOD at desired wavelength, lambda1
