The worldwide aerosol robotic network (AERONET) of ground-based radiometers was developed (in part) as a satellite validation tool (Holben et al. 1998).

The use of the almucantar sky radiance scans in conjunction with the aerosol optical thicknesses are the basis of the AERONET Dubovik retrievals, which provide the aerosol size distribution and the refractive index at four wavelengths (Dubovik and King 2000). The accuracy of the Dubovik retrieval has been assessed with the retrieval of synthetic data (Dubovik et al. 2000), but an assessment utilizing independent measurements is desirable.
