Fig. 3: Comparisons of OA factors between deweathered and observed results.
From: Staggered-peak production is a mixed blessing in the control of particulate matter pollution

a Mass concentrations and b fractions of deweathered and observed OA factors during the NPhs, SPhs and NPnhs. The observed and deweathered change ratios of OA factors between c NPhs and SPhs, d SPhs and NPnhs (The bars below the horizontal line represent increased ratios and the bars above the horizontal line represent decreased ratios of OA factors).
