absorbing aerosols as one can see in Fig. 6 (For example, for a surface albedo of 0.4 and aerosol<br />
model with a single scattering albedo of 0.81, the TOA reflectance decreases with the AOT) The<br />
aerosol model is assumed to be continental and the accuracy of the retrieved AOT is ±0.13 when<br />
compared to AERONET data. A global analysis for one year of data suggests that the optimal<br />
composite time period is around 14 days and that a continental aerosol model is most of the time<br />
well adapted for the retrieval of an AOT. Almost no bias is found between GOES and AERONET<br />
AOT's when the surface reflectance reference is found after applying a residual aerosol correction<br />
using a background AOT of 0.02.<br />
