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 »

Remote sensing has become an indispensable tool for various applications, including environmental monitoring, urban planning, and disaster management, and many more. With the increasing availability of high-resolution satellite and aerial imagery, there is a pressing need for advanced image analysis techniques. Traditionally, convolutional neural networks (CNNs) have dominated the field of computer vision; however, vision transformers (ViTs) have emerged as Continue Reading »

In India, the active areas with Landslides in the Himalayan region and the ongoing process of development in this area can be impeded by the associated risks and hazards posed by these events. The Garhwal Himalaya region, in particular, has a history of landslides, some of which are well-known and triggered by co-seismic events. While rainfall and earthquakes are commonly Continue Reading »

In optical sensors, the features can be seen in the raw data with some radiometric and geometric distortions but SAR raw data are unfocused images where no feature can be seen in the image. Unlike optical sensors, signal processing algorithms are required to focus the SAR raw data. The processing of SAR raw data is always a challenge because it Continue Reading »

El Niño is a buzzword in year 2024 which is a climatic phenomenon characterized by the periodic warming of the central and eastern equatorial Pacific Ocean, leading to substantial global changes observed in weather patterns. Due to El Niño effect in year 2024, the scorching heat is observed in various parts of the world specially in India the large section Continue Reading »
