Fig. 9From: Southern Hemisphere mid- and high-latitudinal AOD, CO, NO2, and HCHO: spatiotemporal patterns revealed by satellite observationsSpatial distribution of linear trends (top, ×1014 molecule cm−2year−1) and p values (bottom) for deseasonalized tropospheric NO2 results in the Southern Hemisphere (30–60° S) from 2005 to 2016. The first column shows the annual trend; other columns show seasonal trends. The regions showing statistically significant trends are colored deep purple (p < 0.05) or light purple (p < 0.10)Back to article page
