Critical Analysis of Physical Properties of Aerosols Models in Different Environments
Author : Vanitha B
Abstract :
Aerosols play a critical role in atmospheric processes, impacting climate, air quality, and human health. This research paper provides a comprehensive analysis of the physical properties of aerosols across different environments-urban, rural, marine, and desert-using various models such as CMAQ, GOCART, and AER-2D. Data were collected from satellite observations, ground-based monitoring networks, and laboratory measurements. The study found significant variations in aerosol properties: urban aerosols exhibited high concentrations of PM2.5 and black carbon with significant light absorption; rural aerosols had a higher proportion of coarse particles and lower fine particulate matter; marine aerosols were dominated by sea salt and sulphates with strong scattering properties; and desert aerosols were characterized by mineral dust with notable scattering and absorption. The findings emphasize the need for region-specific aerosol parameterizations in climate models and stringent air quality regulations to mitigate health risks in urban areas. The study also highlights the importance of international cooperation to address transboundary aerosol pollution. Future research should focus on enhancing data collection, refining aerosol models, and investigating the complex interactions between aerosols and climate. By improving our understanding of aerosol behaviour, this research aims to contribute to more effective environmental policies and mitigation strategies.
