Fig. 2: Comparisons of PM1 species 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 PM1 species during the NPhs, SPhs, and NPnhs. The observed and deweathered change ratios of PM1 species 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 PM species).
