Abstract Envisat/SCIAMACHY instrument have been validated by balloon-borne measurements of the same quantities using the same optical technique. The balloon-borne measurements greatly helped to obtain an accuracy of better than 5 % for the targeted level 1 products (Gurlit et al. 2005; Weidner et al. 2005). Comparison studies with preliminary level 2 retrievals are encouraging. For the individual profiles, the comparisons indicate an accuracy of ±20 % for O3 and NO2 (Butz et al. 2006). For BrO a bias of-20 % / +20 % is observed for altitudes above/below 25 km, respectively (Dorf et al. 2006). The results depend on the individual species, considered wavelength range, profile height and geophysical condition of the measurements. 1.
