Authors: Dr.  Suresh Kumar and Dr. R. P Singh, IIRS Urbanization is reshaping the earth planet, with nearly 70 percent of the global population expected to live in cities by 2050. India’s urban population was 36.36% in 2023 and expected to reach 50% by 2050. As cities continue to grow, they face increasing environmental challenges such as solid waste, industrial Continue Reading »

Authors- Ashutosh Bhardwaj, Hari Shankar Srivastava and Raghavendra Pratap Singh Spaceborne LiDAR datasets are contributing immensely for the topographic, ice mass-balance and vegetation related studies. It provides a global view of changes occurring in elevation over Earth. CartoDEM Version 3 Release 1 openly accessible datasets are currently the most reliable datasets for the relatively plain regions in India. The study Continue Reading »

Dust storms originating in arid or semi-arid regions play a critical role in modulating regional climate, surface reaching solar radiation, atmospheric chemistry, and marine ecosystems through long-range transboundary transport. When mineral dust trails traverse continental landmasses and oceanic basins, they alter atmospheric radiative balances, degrade air quality and deposit essential nutrients onto open ocean, driving bio-geochemical feedback loops. Understanding these Continue Reading »

Diagnostic absorption spectroscopy across the Visible, Near-Infrared, and Shortwave Infrared (VNIR–SWIR: 0.4–2.5 µm) regimes enables rapid, non-destructive chemical and mineralogical characterization of lithological units. In this investigation, airborne imaging spectrometer data from AVIRIS-NG were integrated with laboratory-based spectroradiometric measurements to map and discriminate limestone sub-types within the metasedimentary sequences of the Kalinjara Formation, Aravalli Supergroup. By quantifying diagnostic absorption band Continue Reading »
