Dr. Dipanwita Haldar | November 27, 2024 | 254 Views
Dipanwita Haldar and Suresh Kumar Medium resolution SCANSAR (MRS) data 18m pixel spacing has served as work horse for field crop monitoring during 2012-2016 during RISAT-1 timeframe and 2022 onwards in RISAT-1A particularly for predominant kharif crops’s monitoring. This dataset is being systematically acquired over the entire Indian subcontinent in descending node. During the overcast sky in the northern India, Continue Reading »

Estimating aerosol loading from satellite signals – A simplified Physics based approach

Dr. Manu Mehta | June 10, 2024 | 238 Views
Manu Mehta and Akhilesh Kumar Estimating atmospheric aerosol levels is crucial for accurate radiative forcing calculations, understanding aerosol effects on cloud formation, assessing human health impacts, and planning pollution control. Continuous monitoring of aerosols in both space and time is essential to understand its effects in human life. Ground-based networks like AERONET and ARFINET use instruments such as sun-photometers and Continue Reading »

Life of earth is linked to availability of water and rivers provides water to sustain the human civilization. Ganga river is one of the longest river in India and  is associated with sediment transport and meandering. Ganga river originate in the Himalayas, and it carries lot of sediments. Sediment deposition prevent  any river from flowing straight and cause meander. Gandak Continue Reading »

Raman Spectroscopy and its Scope in Planetary Exploration

Dr. Mamta Chauhan | December 12, 2024 | 195 Views
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 »
