“…123 Both types of carbonaceous aerosols can be transported across the globe and persist in the atmosphere for days to weeks. 63,64 Inclusion of emissions from fires in climate models increased the predicted global mean annual aerosol optical depth at visible wavelengths by 10%. 124 Besides their role as condensation nuclei in the formation of clouds, aerosols may also interact with cloud droplets resulting in changes in the albedo of clouds, which in turn affects the fraction of solar radiation scattered upwards.…”

“…Reduced concentrations of aerosols have already been observed during the last two decades over urban areas in Europe and Eastern USA. 64 At some of these locations, where measurements of UV irradiance were available, the reduced aerosols have led to increases in UV radiation, as discussed in section 4. The effect of the projected increases in total ozone above the pre-ozone-depletion levels due to increasing GHGs contributes from 0 to −8% to the projected decreases in UVI.…”

“…Air pollution has health impacts across the life course. It has been associated with adverse birth outcomes, reduced lung function, respiratory and cardiovascular diseases, and more recently, diabetes, autism, dementia, and reduced cognitive function [93][94][95][96]. Despite the relatively low levels of PM 2.5 in Australia, significant associations between air pollution and human health impacts have been observed in Sydney and other parts of Australia [11,22,[97][98][99].…”

This paper presents a summary of the key findings of the special issue of Atmosphere on Air Quality in New South Wales and discusses the implications of the work for policy makers and individuals. This special edition presents new air quality research in Australia undertaken by (or in association with) the Clean Air and Urban Landscapes hub, which is funded by the National Environmental Science Program on behalf of the Australian Government’s Department of the Environment and Energy. Air pollution in Australian cities is generally low, with typical concentrations of key pollutants at much lower levels than experienced in comparable cities in many other parts of the world. Australian cities do experience occasional exceedances in ozone and PM2.5 (above air pollution guidelines), as well as extreme pollution events, often as a result of bushfires, dust storms, or heatwaves. Even in the absence of extreme events, natural emissions play a significant role in influencing the Australian urban environment, due to the remoteness from large regional anthropogenic emission sources. By studying air quality in Australia, we can gain a greater understanding of the underlying atmospheric chemistry and health risks in less polluted atmospheric environments, and the health benefits of continued reduction in air pollution. These conditions may be representative of future air quality scenarios for parts of the Northern Hemisphere, as legislation and cleaner technologies reduce anthropogenic air pollution in European, American, and Asian cities. However, in many instances, current legislation regarding emissions in Australia is significantly more lax than in other developed countries, making Australia vulnerable to worsening air pollution in association with future population growth. The need to avoid complacency is highlighted by recent epidemiological research, reporting associations between air pollution and adverse health outcomes even at air pollutant concentrations that are lower than Australia’s national air quality standards. Improving air quality is expected to improve health outcomes at any pollution level, with specific benefits projected for reductions in long-term exposure to average PM2.5 concentrations.

Greenhouse gas‐induced global warming represents one of the most pressing environmental challenges currently faced, with methane, a primary constituent of greenhouse gases, exerting a more potent greenhouse effect than carbon dioxide. Precise prediction of methane concentrations is therefore of paramount importance. Owing to the complex interplay of factors affecting methane levels, existing forecasting methodologies often fall short in terms of accuracy and long‐term applicability. In response, this article leverages a multiscale time series to propose an attention‐based deep learning model. This approach synthesizes data across varied time spans, enhancing the extraction of periodic patterns and inter‐scale feature correlations. The model employs a hybrid framework and attention mechanisms to adaptively discern both short‐ and long‐term dependencies, as well as spatiotemporal correlations, capturing the intricate coupling of change mechanisms in the environment. Focusing on the Yanqing district of Beijing, a dataset integrating multiple features is developed and conduct forecasts 48 h in advance for both surface methane concentrations and the average molar fraction of total methane columns, comparing our model against several benchmarks. The model demonstrates superior performance, achieving an RMSE of 5.6123, MAE of 3.4959, and an R2 of 0.9148, which significantly exceeded the accuracy and generalizability of all baseline models.
