This book describes the continuous observation of prominent trace gases O3, and its precursors like NO, NO2, NOx, CH4 and Total NMHCs that significantly influence the air quality over Kannur, a coastal region in South India. Ozone being a prominent greenhouse gas, it plays a vital role in modifying the chemistry of the atmosphere by which it induces climate changes. Further, this highlights abrupt variations of O3, and NOx in the context of varying meteorological parameters during the annular solar eclipse on 15th January 2010. Likewise, air pollution formed out of the coordinated fireworks...

This book focuses on the optical properties of atmospheric aerosols, their diurnal and seasonal variations that have been observed at Kannur (11.9oN, 75.4oE, 5 m ASL). This work has been carried out with the ground based measurements by using a sun photometer. Measurement of aerosol mass loading and chemical analysis for identifying and quantifying various inorganic chemical species gives more insight to formulate a model suited for this region. The results were quite positive in climate models to study the impact of aerosols on the atmospheric radiation balance. The results of the chemical...
