Abstract
The present paper describes a UV-VIS spectroradiometer named GASCOD/A4r developed at ISAC-CNR for
remote sensing measurements aboard stratospheric M55-Geophysica aircraft, flying up to 21 km. Obtained experimental
data are used for retrieving of NO2, O3 and of other minor gases atmospheric content, applying the
DOAS (Differential Optical Absorption Spectroscopy) method. UV actinic flux and J(NO2) are also derived. All
these parameters are used for satellite data validation tasks. The specific results obtained during dedicated aircraft
missions in different geographical areas have already been utilized for ENVISAT validation
