Assessments of the impacts of ozone (O 3 ) on regional and global food production are currently based on results from experiments using open‐top chambers ( OTC s). However, there are concerns that these impact estimates might be biased due to the environmental artifacts imposed by this enclosure system. In this study, we collated O 3 exposure and yield data for three major crop species—wheat, rice, and soybean—for which O 3 ex...

We investigated the effects of elevated ozone concentration (E‐O 3 ) on CH 4 and N 2 O emission from paddies with two rice cultivars: an inbred Indica cultivar Yangdao 6 ( YD 6) and a hybrid one II ‐you 084 ( IIY 084), under fully open‐air field conditions in China. A mean 26.7% enhancement of ozone concentration above the ambient level (A‐O 3 ) significantly reduced CH 4 emission at tillering and flowering stages leading to a...

Using a high‐resolution (40 × 40 km) chemical transport model coupled with the Regional Emission inventory in A sia ( REAS ), we simulated surface ozone concentrations ([ O 3 ]) and evaluated O 3 ‐induced wheat production loss in China and India for the years 2000 and 2020 using dose–response functions based on AOT 40 (accumulated [ O 3 ] above 40 ppb) and POD Y (phytotoxic O 3 dose, accumulated stomatal flux of O 3 above a th...
