^aRelationships between daily NO₂ inequalities, surface NO₂*, and NO₂ TVCDs are Pearson correlation coefficients (r). All other relationships are Spearman rank correlation coefficients (ρ). Correlations are separately analyzed in the winter (December–February) and summer (June–August) for days with TROPOMI observations with >60% UA coverage. Only statistically significant coefficients are reported, with r and ρ significant to 1% (p < 0.010) unless indicated as (†), which means significant to 5%.
