A multi-input UV-VIS airborne GASCOD/A4r spectroradiometer for the validation of satellite remote sensing measurements

摘要

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