Tropospheric Ozone Assessment Report II: Past and present tropospheric ozone using satellite observations

Satellite observations enable global assessments of ozone in the free troposphere, yet uncertainties in earlier records limited the first Tropospheric Ozone Assessment Report's (TOAR-I) confidence in regional distributions and, especially, decadal trends. Here, we leverage longer...

Assessing the Impact of Incorporating Bias-Adjusted Satellite Observations into Global Data Fusion for Ground-level Health-Related Ozone Metrics

Understanding global ground-level ozone is hindered by significant monitoring gaps. To address this, we introduce a Bayesian Maximum Entropy data fusion framework that includes satellite ozone observations, generating a global 0.1° surface ozone dataset (2005–2022). Satellite obs...
