pvlib.atmosphere.bird_hulstrom80_aod_bb(aod380, aod500)[source]

Approximate broadband aerosol optical depth.

Bird and Hulstrom developed a correlation for broadband aerosol optical depth (AOD) using two wavelengths, 380 nm and 500 nm.

Parameters:
  • aod380 (numeric) – AOD measured at 380 nm. [unitless]
  • aod500 (numeric) – AOD measured at 500 nm. [unitless]
Returns:

aod_bb (numeric) – Broadband AOD. [unitless]
