AB: Tropospheric NO2 columns from SCIAMACHY are retrieved using the reference sector and nadir-limb subtraction methods during the INTEX-NA (North America) campaign in July and August of 2004. The TD-LIF (thermal dissociation laser-induced fluorescence) instrument measured NO2 vertical profiles in-situ during ascents and descents by the DC-8 during INTEX-NA. Tropospheric profiles measured by the TD-LIF technique are vertically integrated to provide in-situ tropospheric columns. A three-way comparison is performed between SCIAMACHY reference sector, nadir-limb matching and TD-LIF techniques.
