The transport and dispersion of pollutants becomes weak under low wind conditions resulting in large ground level concentrations (g.l.c.'s). Largest mean g.l.c.'s due to elevated sources are typically found under daytime ...

A study of concentrations of sulfur dioxide (SO2) and suspended particulate matter (SPM) has been performed in Delhi. The monthly and seasonal variations of concentrations and winds are analyzed. The monthly mean SO2 ...

A line source model, developed in Indian Institute of Technology (IIT) Delhi, India, namely IIT line source (IITLS) model, is proposed to describe the downwind dispersion of pollutants near roadways along with a brief ...

Traffic is the predominant source of pollution in urban cities like Delhi. Continuous monitoring of the air quality in roads will be very costly and impracticable. To carry out model calculations is a useful alternative ...

A comparative study between predicted and observed concentrations of major pollutants SO2, suspended particulate matter (SPM) and NOx in Agra, India has been undertaken using two Gaussian plume models. A Gaussian plume ...

The present study discusses the ambient air quality of Delhi from the point of view of change of diesel by Compressed Natural Gas (CNG) in transportation in Delhi. Several initiatives were taken to reduce extremely high ...

The present work focuses on the seasonal evaluation of suspended particulate matter (SPM) produced by Badarpur thermal power station (BTPS) within a radius of 5 km of its source. The study was carried out using both ...
