Unraveling overestimated exposure risks through hourly ozone retrievals from next-generation geostationary satellites [PDF]

Nature Communications
Accurate ground-level ozone (O3) estimation is crucial for assessing health impacts and designing control strategies. Traditional polar-orbit satellites provide limited, one-time measurements, missing O3’s diurnal variability.
