Ozone Column in India

The stratosphere, a region above the weather producing layer—troposphere contains around 90 per cent of the earth’s ozone. Depletion of this stratospheric ozone leads to deleterious environmental effects, thus necessitating continuous monitoring. The ozone column above the Indian subcontinent has been examined since 1970 and measurements show that although the total ozone content has not […]

Climate Change and Indian Forest

Climate is one of the most important determinant of vegetation patterns globally and has a significant influence over distribution, structure and ecology of forests. Several climate-vegetation studies have shown that climatic regimes are associated with particular plant communities or functional types. It is therefore logical to assume that changes in climate would alter the distribution […]

Asian brown clouds, climate change and reduced rice harvests in India

The combined effects from atmospheric brown clouds (ABC), and of the global increase in greenhouse gas (GHG) concentrations are good examples of complex chemical and physical processes at various scales. ABC block a part of the incoming solar radiation and thereby reduce direct warming effects from GHG. Climate change is an ever more serious issue […]
