Aerosol remote sensing with AATSR: The dual-view ORAC retrieval scheme

Abstract:
The differing path lengths of AATSR's forward and nadir views can be used to separate the contributions from aerosol scattering and surface reflectance in the observed top-of-atmosphere (TOA) radiance. The nadir-view Oxford-RAL retrieval of Aerosols and Clouds (ORAC) scheme has been extended to take advantage of the dual-view capabilities AATSR offers. The new algorithm uses optimal estimation to retrieve aerosol optical depth at 550 nm, effective radius and the white-sky surface albedo at AATSR visible channel wavelengths. A comparison of retrieval results for the month of September 2004 with AERONET and MISR measurements is presented, along with some applications of the data to the Amazon region.
