Currently, there exists a great deal of uncertainty regarding atmospheric aerosols and the role that they play within the Earth’s atmosphere. It is known that atmospheric aerosols can play a role in the Earth’s climate by scattering and absorbing solar radiation or acting as a cloud condensation nuclei. The purpose of this work is to obtain an improved understanding of the chemistry of atmosphe...

The Coastal Aerosol Transport (CAT) model was developed to study the evolution of aerosol particle size distributions and composition in the coastal environment. The model simulates such processes as particle production at the sea surface, mixing of particles through the boundary layer by turbulent diffusion, gravitational settling, and dry deposition. The model is initialized at the shoreline ...

During the last decade much attention has been focused on anthropogenic aerosols and their radiative influence on the global climate. Charlson et al. (1992) and Penner et al. (1994) have demonstrated that tropospheric aerosols and particularly anthropogenic sulfate aerosols may significantly contribute to the radiative forcing exerting a cooling influence on climate which is comparable in magni...

A global aerosol model with relatively high resolution is used to simulate the distribution and radiative effect of aerosols during the Aerosol Direct Radiative Impact Experiment (ADRIEX) campaign in August and September 2004. The global chemical transport model Oslo CTM2 includes detailed chemistry, which is coupled to aerosol partitioning of sulphate, nitrate and secondary organic aerosols. I...

Antarctica provides an excellent environment to examine the natural and background aerosols in the atmosphere over snow and ice. The Indian efforts (metrological measurements) at Antarctica were initiated with the establishment of the first Antarctic station in Eastern Antarctica during the first Indian Scientific Expedition to Antarctica (ISEA) in 1981. The detailed and systematic characteriza...

Measurements of both horizontal gradients and vertical profiles of aerosols, cloud droplets and thermodynamic parameters in the cloud topped marine boundary layer off of central California are presented. They suggest that, while aerosols can indeed modulate cloud albedo, other parameters such as sea surface temperature may similarly affect cloud albedo. Additionally, the impact of aerosols, thr...

Atmospheric aerosols are important from a perspective of ambient air pollution and health to humans and other biological receptors as well as for potential effects on local weather and global climate. This review attempts to account for the different research efforts of individual research groups and regulatory agencies in India on the issue of atmospheric aerosols and their effects. The review...

More than three decades have passed since the launch of the first satellite instrument used for atmospheric aerosol detection. Since then, various powerful satellite remote sensing technologies have been developed for monitoring atmospheric aerosols. The application of these new technologies to different satellite data have led to the generation of multiple aerosol products, such as aerosol spa...
