Anthropogenic Aerosols and their Impact on Climate Change

About this Research Topic

Due to the rapid increase of industrialization and urbanization in the last few decades, air pollution has become one of the most critical crises of the 21st century, affecting regional air quality, atmospheric visibility, agricultural crop production, and have a significant potential to affect the global climate. Urban areas of developing countries (like India, China, and Brazil, etc.) are the major source regions of these anthropogenic emissions and are heavily polluted throughout the year. Under suitable meteorological conditions, these pollutants can also trigger pollution events that reduce the local air quality, atmospheric visibility and are hazardous for human health. Atmospheric aerosols (also known as particulate matter) are one of the crucial components of air pollution and play a vital role in global climate change through different pathways. The impacts of atmospheric aerosols on local air quality, as well as regional and global climate change, are highly dependent on their chemical composition and spatiotemporal variability of optical and microphysical characteristics due to various emission sources and are hence associated with large uncertainty.

Anthropogenic aerosols also have significant potential to perturb both the hydrological cycle, by affecting monsoonal circulation patterns, and the biogeochemical processes of the oceanic region through the supply of macro and micronutrients. Thus, they can modulate the food chain and eventually our marine bio-resources, and hence the country’s economy. Therefore, accurate information of the physiochemical characteristics of aerosols, their composition, morphology, and source apportionment will be helpful for a better understanding of anthropogenic aerosols' impact on global climate change, surface ocean biogeochemistry, and sustainable development.

This Research Topic aims to cover the physiochemical characteristics of atmospheric aerosol, their source apportionment, and long-range transportation using synergistic approaches of state-of-the-art in situ measurement techniques, space-borne measurements, and modeling results. We also welcome research articles covering aerosol chemistry and morphology, short-term campaigns-based, and case study. Furthermore, articles submitted to this issue can also include the role of anthropogenic aerosol on ocean biogeochemistry and the Indian Summer Monsoon (ISM). The articles should have focused objectives and be supported with a statistically significant dataset.

We invite the authors to contribute research on the following topics:
• Physiochemical characteristics of atmospheric aerosol, their composition, morphology, and source apportionment.
• In situ, space-borne measurement and modeling study of aerosol.
• Optical, morphology, and mixing state of individual particles in various atmospheric environments.
• Impacts of anthropogenic emissions on the marine environment.
• Anthropogenic emissions and Indian Summer Monsoon (ISM).
• Anthropogenic emission mitigation policies, climate change, and sustainable development of coastal environments.


Keywords: Atmospheric Aerosol, Anthropogenic Emission, Aerosol Composition, Aerosol Individual Particle, Sustainable Development, Climate Change, Indian Summer Monsoon
