    • AERONET-SDA Retrievals

    Metadata Updated: November 14, 2025

    The SDA dataset uses the spectral behavior of AOD to partition between fine and coarse modes, without a size-cutoff radius of the type used by the Dubovik and King [2000] inversion algorithm. The SDA data are derived from the direct-Sun observations rather than almucantar scans. Datasets are available at annual, monthly and daily accrurals.
