From: Large-scale impacts of the 2023 Canadian wildfires on the Northern Hemisphere atmosphere
a Global May-September average differences (FIRE – noFIRE) for the parameter: AOD. b Averaged NH regional longitudinal analysis of anomalies for the parameter: AOD. c Demonstration of chosen sub-regions for longitudinal analysis. Hatching in Fig. 2a represents the application of a typical Student’s t-test for statistical significance.
