Authors- Deepak Putrevu, Tathagata Chakraborty and DFSAR team, Space Application Center, ISRO Ahmedabad. Radar studies of the lunar surface have so far been restricted to Earth-based radio telescopes and Moon-orbiting sensors operating with limited polarimetry configuration. The Dual-frequency Synthetic Aperture Radar (DFSAR) onboard Chandrayaan-2 (Ch-2) orbiter is the first ever state-of-the-art high-resolution radar system in the lunar orbit. To this 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 »

Author: Ashish Joshi, IIRS An oil spill is one of the worst environmental disasters which affect marine ecosystems due to anthropogenic activities. Oil spills can be detected, monitored, and studied using various types of remote sensing techniques. Synthetic Aperture Radar (SAR) is widely used in oil spill detection due to its all-weather and all-time capabilities. Oil Spills have a smooth Continue Reading »

Authors: Ashish Joshi, Shefali Agrawal, R. P. Singh Glaciers are massive bodies of ice formed over many years from compacted snow that slowly flows downhill under the force of gravity. Glacial lakes are formed from melting glacier ice. They can be found on top of glaciers, inside or beneath them, or in front of and beside glaciers. These lakes are Continue Reading »
