In February 2024, National Aeronautics and Space Administration (NASA) launched the most advanced Earth-observation satellite namely PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), for the better understanding of ocean productivity and the impact of global warming induced climate change. The mission carries a hyperspectral radiometer along with multi-angle polarimeters. The Ocean Color Instrument (OCI) is a hyperspectral imaging radiometer gives the Continue Reading »

Introduction of irrigated rice in the semi-arid northwest Indian region is one the major changes in Indian agriculture.  Punjab and Haryana has witnessed significant change in cropping pattern during the last few decades.  Increase in rice area is of particular significance. The State of Punjab occupies a special place in Indian agriculture. Rice- wheat rotation followed in Punjab leaves little Continue Reading »

Current sensing technology operates within the electromagnetic spectrum, covering wavelengths ranging from tens of micrometers to meters. However, newer Remote Sensing (RS) instruments utilizing quantum sensing at the Nano to Femto scale are set to unveil internal structures of objects, necessitating a shift towards quantum spectral domain in Remote Sensing. Quantum remote sensing involves theories and methods that observe energy Continue Reading »

Justin George K and Suresh Kumar Proximal soil sensing involves using sensors placed close to or within the soil to measure its properties accurately and efficiently. Proximal sensing approaches employing various advanced sensors aid us in acquiring spatial as well as temporal soil data/information at reduced costs, in very short time period and with reduced chemical usage and less efforts.

Snow cover plays an important role both globally and regionally as it reflects a large portion of the insolation, therefore keeping the Earth’s radiation budget in balance. Snow cover is important for local water availability, river run-off and groundwater recharge, especially in middle and high latitudes. Glaciers are mass of snow, ice, water and rock debris slowly moving down a Continue Reading »
