Figure 1. (a) Curtain plots for P-O3 (0-6 ppb/d) showing the profiling of the 4 ATom deployments over the Pacific Ocean (54°S-60°N). (b) Mean altitude profile of P-O3 over the 3 tropical ocean basins (30°S-30°N) for the 4 ATom’s. (c) Probability densities of relative humidity over liquid water (RHw, 0-110%) in the lower troposphere (0-6 km) in the 3 tropical basins for the 4 ATom’s. Color coding in the legend identifies the 4 ATom deployments. The numbers in the legend of panel (c) are, successively, the mean value, standard deviation, and skewness.
