Analysis of ACAM Data for Trace Gas Retrievals during the 2011 DISCOVER-AQ Campaign

Figure 2

(a) Difference between ACAM () and simulated () radiance versus wavelength for 158 ozonesonde/ACAM collocations (within 2 hours and 1 km) in different colors, for the 2011 DISCOVER-AQ flight campaign. The average difference (black) is used as the empirical radiometric correction. (b) Retrieved total ozone column with (black) and without (red) using the derived empirical correction from ACAM radiance in the spectral region 318–335 nm from July 21, 2011, using the optimal estimation based ozone profile algorithm.
