Monthly TOB (Tg) per latitude band. Monthly tropospheric ozone burden (TOB) (thin curves) for 60°S–60°N (top), 00°N–60°N (middle), and 00°S–60°S (bottom), for seven different satellite products. Thick curves are the 12-month running means and the thin straight lines are the least square linear fits. Trends (Tg yr^–1) in this figure are based on least-squares linear regression and reported with 95% confidence intervals and p-values. DOI: https://doi.org/10.1525/elementa.291.f26
