Tropospheric Ozone Assessment Report: Global Ozone Metrics for Climate Change, Human Health, Crop and Ecosystem Research

This research paper outlines the scientific basis for selecting and applying specific metrics to assess the spatial and temporal variations of tropospheric ozone and its impacts on human health, vegetation, and climate.

• The Tropospheric Ozone Assessment Report (TOAR) utilizes 25 distinct metrics to evaluate ozone, categorized into four groups: 4 for model-measurement comparison, 5 for the free troposphere, 11 for human health impacts, and 5 for vegetation impacts.
• To ensure robust results across thousands of global monitoring sites, the study employed the non-parametric Mann-Kendall test to identify significant trends and the Theil-Sen estimator to determine the magnitude of those trends.
• The choice of metric can lead to different conclusions regarding the effects of ozone variability drivers, such as precursor emissions, because different metrics respond differently to changes in the distribution of hourly average ozone concentrations.
