Mamta Chauhan, Saswati Panda, Ankita Gaur, R.P. Singh and R. S. Chatterjee Raman spectroscopy is an analytical technique to identify mineral, rocks and detect associated organic compounds. This technique is based on the phenomenon of raman effect which causes frequency difference between the incident and the fraction of scattered light. It is inelastic scattering of light by matter in which Continue Reading »

This dataset is being systematically acquired over the entire Indian subcontinent in descending node. During the overcast sky in the northern India, Continue Reading »

Forests, often referred to as the "lungs of the planet," play a crucial role in regulating the Earth’s climate and sequestering carbon dioxide. To understand the effects of climate change and formulate mitigation measures, it is important to know how climate change affects the biogeochemical cycles of forest, especially carbon and water cycles that sustain life on our planet. In Continue Reading »
