pvlib.atmosphere.angstrom_aod_at_lambda(aod0, lambda0, alpha=1.14, lambda1=700.0)[source]#

Get AOD at specified wavelength using Angstrom turbidity model.

Parameters

  • aod0 (numeric) – Aerosol optical depth (AOD) measured at wavelength lambda0. [unitless]

  • lambda0 (numeric) – Wavelength corresponding to aod0. [nm]

  • alpha (numeric, default 1.14) – Angstrom \(\alpha\) exponent corresponding to aod0. [unitless]

  • lambda1 (numeric, default 700) – Desired wavelength. [nm]

Returns

aod1 (numeric) – AOD at desired wavelength lambda1. [unitless]
