Current atmospheric aerosol research in India
نویسنده
چکیده
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 refers to representative studies reporting the physical characterization (size), chemical composition (organic and inorganic), radiative forcing effects and health effects of aerosols. There are several reports on source apportionment studies identifying sources of aerosols and some focus on specific issues. The review also points out a significant need for more data with a greater spatial and temporal resolution for better understanding of the dynamics of atmospheric aerosols in the Indian context.

Metal Signature of Atmospheric Aerosol from Kochi, the Queen of Arabian Sea, Kerala, India
The present research article highlights the metal (Cd, Cu, Pb, Zn and Fe)distribution pattern in the RSPM generated in different hot spot sites located at Kochi, theQueen of Arabian Sea. These sampling sites are categorized under three different zonesas estuarine, riverine, and coastal. Two sampling phases are selected in order to check theconsistency in pollution trend after a two year gap and...

متن کاملAerosol black carbon radiative forcing at an industrial city in northern India
[1] During a comprehensive aerosol field campaign as part of ISRO-GBP, extensive measurements of aerosol black carbon were made during December 2004, for the first time, at Kanpur, an urban continental location in northern India. BC diurnal variation is associated with changes in boundary layer mixing and anthropogenic activities. BC concentration in Kanpur is comparable to those measured in ot...
متن کاملEvolution of aerosol research in India and the RAWEX–GVAX: an overview
Climate change has great significance in Asia in general, and India in particular; and atmospheric aerosols have a decisive role in this. The climate forcing potential of aerosols is closely linked to their optical, microphysical and chemical properties. Systematic efforts to characterize these properties over the Indian region started about 5 decades ago, and evolved over the years through con...
متن کاملThe formation, properties and impact of secondary organic aerosol: current and emerging issues
Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric aerosol and a detailed knowledge of the formation, properties and transformation of SOA is therefore required to evaluate its impact on atmospheric processes, climate and human health. The chemical and physical processes associated with SOA formation are complex and varied, and, despite considerable prog...
