Aerosol Optical Depth (AOD)

─ Comparison between esimated AOD & Level 1.5 (cloud screened) AERONET data:

  ① Interpolate AERONET measurements at λ=550 nm using the Angstrom Exponent

  ② Average AERONET values over time period of +/- 15min  from AOD retrieved values (L-8/S-2 overpass)

  ③ Average AOD estimates over an image subset of 9 km x 9 km centred on the AERONET Sun-photometer station
