Comparison of O3 (left), CH2O (middle column), and NO2 (right) fitting in (top) relative RMS, (middle row) SCDs, and (bottom) precision of SCDs for ACAM measurements from July 21, 2011, using three different reference spectra: average zenith reference (blue), high-resolution solar irradiance convolved with instrument slit functions (black), and derived TOA solar irradiance from average nadir radiance spectrum (red).
