The riverine alluvial grasslands of The Kaziranga National Park and Tiger Reserve (KNPTR) are home to at least 2,400 one-horned rhinos and support an assemblage of eight mega- and meso-herbivores. Annual floods and monsoon clouds are an essential part of Kaziranga’s delicate ecosystem. Kaziranga exists due to the monsoon, and so is the cloud. With their large body size, the Continue Reading »

Authors: Sreyasi Biswas and Charu Singh An Atmospheric River (AR) is a long, narrow, and transient filament of enhanced water vapour that transports fresh water from the tropics into the mid-latitudes (Figure 1). These are popularly called ‘Rivers in the Sky’ because like a river, it carries a huge volume of water. In fact, if all its water vapour were Continue Reading »

The Forestry and Ecology Department of IIRS established 15 Open Top Chambers (OTC) in September 2022 at Gangotri, Uttarakhand, to delve into the intricate dynamics of Himalayan Alpine Biological Communities under the influence of Experimental Warming. The idea is to test the impact of warming on plant phenology, plant height, biomass and nutrient concentration between OTCs and control plots. Preliminary Continue Reading »

Since the beginning of the industrial era, the anthropogenic carbon dioxide (CO2) concentration has been steadily increasing in the atmosphere caused by deforestation, fossil fuel, biomass burning, cement manufacturing, various land-use practices, and other anthropogenic activities. The ocean absorbs one-third of the total anthropogenic CO2 from the atmosphere and plays an important role in the mitigation of global warming and Continue Reading »

Digital Elevation Models (DEMs) are crucial for studying natural phenomena. Recent research at IIRS has focused on enhancing DEMs through advanced techniques like combining data from Remote Sensing, Satellite Photogrammetry, and SAR Interferometry (InSAR/IfSAR), as well as Spaceborne LiDAR. Notably, studies in the Ghaziabad and Dehradun regions have shown significant improvements in DEMs through fusion methods. Analyzing fused DEMs from Continue Reading »
