About this Research Topic
People living in urban areas are still suffering from the effects of air pollution in most metropolitan regions world-wide. Despite efforts to reduce emissions, ongoing climate change and accompanying heat waves will potentially worsen this impact by, increasing human sensitivity to pollution, decreasing pollution transport out of the city, and favoring ozone formation. Therefore, urban and suburban greening, including trees, hedges, lawns, green walls and roofs, has been proposed to counteract these effects but the actual benefit of a specific measure on air quality is largely uncertain.
The Research Topic addresses the direct and indirect quantification of impacts that green spaces, in cities and surrounding forests exert on air quality. The range of pollutants spans from anthropogenic and biogenic released or secondary formed particles and gaseous compounds and the effects of interest include direct ones such as deposition and delayed transport, in addition to indirect ones such as decreased ozone formation due to shading and cooling. We also welcome studies that address air pollution impacts on plants, if responses are induced that feed back into air quality.
This Research Topic welcomes articles in accordance with the outlined scope. Manuscripts are welcomed from various fields such as biology, air chemistry, human health, urban planning, and remote sensing, independent from whether they are based on measurements or modelling.
