Trends and characteristics of ozone and nitrogen dioxide related health impacts in Chinese cities

Ecotoxicology and Environmental Safety, 2022
Ambient ozone pollution has been becoming severe and attributed to considerable health impacts in China. Nitrogen dioxide (NO2) is involved in atmospheric ozone production while also affecting public health directly. Joint control ozone and NO2 pollution

Functional indicators of response mechanisms to nitrogen deposition, ozone, and their interaction in two Mediterranean tree species [PDF]

, 2017
The effects of nitrogen (N) deposition, tropospheric ozone (O3) and their interaction were investigated in two Mediterranean tree species, Fraxinus ornus L. (deciduous) and Quercus ilex L.

Ozone production efficiencies of acetone and peroxides in the upper troposphere [PDF]

Geophysical Research Letters, 1998
HOx concentrations in the upper tropical troposphere can be enhanced by the presence of acetone and the convective injection of peroxides. These enhancements in HOx might be expected to increase ozone production by increasing the rate of the HO2+NO reaction.

Chemical transport model ozone simulations for spring 2001 over the western Pacific: Regional ozone production and its global impacts [PDF]

, 2004
The spatial and temporal variation in ozone production over major source regions in East Asia during the NASA Transport and Chemical Evolution over the Pacific (TRACE-P) measurement campaign in spring 2001 is assessed using a global chemical transport ...

Treatment of spring wheat seeds by ozone generated from humid air and dry oxygen

Research in Agricultural Engineering, 2018
The paper presents an analysis based on conflicting data regarding the results of the treatment of soft spring wheat seeds by ozone generated from humid air and dry oxygen. Morphological characteristics of treated seeds (the length of a sprout, the total

COVID-19 induced lower-tropospheric ozone changes

Environmental Research Letters, 2021
The recent COVID-19 pandemic with its countermeasures, e.g. lock-downs, resulted in decreases in emissions of various trace gases. Here we investigate the changes of ozone over Europe associated with these emission reductions using a coupled global ...

Chemical data assimilation estimates of continental U.S. ozone and nitrogen budgets during the Intercontinental Chemical Transport Experiment-North America [PDF]

, 2007
Global ozone analyses, based on assimilation of stratospheric profile and ozone column measurements, and NOy predictions from the Real-time Air Quality Modeling System (RAQMS) are used to estimate the ozone and NOy budget over the continental United ...

Evaluation of simulated O3 production efficiency during the KORUS-AQ campaign: Implications for anthropogenic NOx emissions in Korea

Elementa: Science of the Anthropocene, 2019
We examine O3 production and its sensitivity to precursor gases and boundary layer mixing in Korea by using a 3-D global chemistry transport model and extensive observations during the KORea-US cooperative Air Quality field study in Korea, which occurred

Observations of ozone production in a dissipating tropical convective cell during TC4 [PDF]

, 2010
From 13 July–9 August 2007, 25 ozonesondes were launched from Las Tablas, Panama as part of the Tropical Composition, Cloud, and Climate Coupling (TC4) mission. On 5 August, a strong convective cell formed in the Gulf of Panama.

How sensitive is tropospheric oxidation to anthropogenic emissions? [PDF]

, 2008
We use a global chemistry transport model to explore how changes in anthropogenic emissions alter ozone production and tropospheric oxidizing capacity over decadal (1990–2010) and centennial timescales (1900–2100).
