Studies of Atmospheric Ozone and Related Constituents in the Arctic and at Mid-latitudes
… (GBSs) were installed at the Polar Environment Atmospheric Research Laboratory (PEARL) in the Canadian High Arctic (80.1o N, 86.4o W). These two instruments have been used to measure stratospheric trace gases since 1999 and 2006 respectively. In 2010 and 2014, two solar-tracking systems were …

On potential effects from the aviation and refrigeration sectors on ozone and climate
… refrigeration sectors contribute to the global ozone budget and to climate change via emissions of relevant gases and particles, subsequently followed by a complex set of chemical and physical processes. For the refrigeration sector, iodotrifluoromethane (CF3I) and methyl iodide (CH3I) are two …

The effects of elevated CO2 and ocean acidification on the production of marine biogenic trace gases
The human-induced increases in atmospheric carbon dioxide since the beginning of the industrial revolution have led to increasing oceanic carbon uptake and changes in seawater carbonate chemistry, resulting in lowering of surface water pH. To date, surface ocean acidity has increased by 30% …

Factors influential in the coverage of environmental issues by the South African press
… of three environmental issues, global warming, atmospheric ozone depletion, and the Sappi paper mill effluent spill into Eastern Transvaal rivers (1989), in two South African daily newspapers, The Star and The Citizen. A combination quantitative-qualitative content analysis was undertaken on …

Genomic and biochemical investigation of soybean antioxidant metabolism in response to growth at elevated carbon dioxide and elevated ozone
… ROS or recycle the antioxidant metabolites. Ozone is a temporally dynamic molecule that is both naturally occurring as well as an environmental pollutant that is predicted to increase in concentration in the future as anthropogenic precursor emissions rise. It has been hypothesized that any …

Interactions between oxidative stresses in corn
… change, including the rise in tropospheric ozone (O3) in agricultural zones, presents a challenge for future global food supply and specifically for one of the most economically important crops in the Midwest region, maize (Zea mays L.). Ozone is the prototypical inducer of oxidative stress, …

Surface Ozone and Population Health
Atmospheric ozone is attracting ever-growing research attention, as i) stratospheric ozone depletion will expose the biosphere to stronger hazardous ultraviolet radiation, which has been emphasised in the Montreal Protocol; ii) ozone as a greenhouse gas can alter the atmospheric thermodynamics; …

Spatial-Longitudinal Bent-Cable Model with an Application to Atmospheric CFC Data
… our methodology with an application to atmospheric chlorofluorocarbon (CFC) data. We also present a simulation study to demonstrate the performance of our proposed methodology. Although we have tailored our work for the CFC data, our modelling framework may be applicable to a wide …
