Study of HCHO/NO2 ratio versus Ozone at ground at San Pietro Capofiume using SkySpec-2D MAX-DOAS measurements

This document is the report of the activities performed in the frame of WPs 2250-1.1, 1.2, 1.3 of the IDEAS-QA4EO WPs-2250-2251 “DOAS-BO: Towards a new FRM4DOAS-compliant site’’ CCN10. The WP 2250-1 is centered on the processing of MAX-DOAS SkySpec-2D measurements at San Pietro Capofiume (therein SPC) “Giorgio Fea” ISAC-CNR observatory in the Po Valley for the retrieval of HCHO (formaldehyde) tropospheric profiles. The main outcomes of these WPs have been reported in D-2A “San Pietro Capofiume HCHO tropospheric profiles and VCDs dataset from SkySpec-2D MAX-DOAS measurements and comparisons with TROPOMI Tropospheric VCDs”.
