AERONET inversion code provides aerosoloptical properties in the total atmospheric column derived from the direct and diffuse radiation measured byAERONETCimel sun/sky-radiometers. AERONET inversion developmentand researchactivitiesare described in the papers by Dubovik and King, [2000], Dubovik et al. [2000], Dubovik et al. [2002a], Dubovik et al. [2002b], Dubovik et al., [2006a], Sinyuk et al. [2006]. The Version 2(V2)inversion (or retrieval)products are summarized below. These products are available through the internal analysis system"demonstrat" and the AERONET website. Adetailed description of V2 AERONET retrieval will be provided in the paper by Dubovik et al., [2006b].
