Blockchain technology is a decentralized and immutable ledger system that enables secure and transparent transactions or data exchanges. It operates on a distributed network of computers, known as nodes, which collectively validate and record transactions in a chronological and tamper-resistant manner. Each transaction, or block, is cryptographically linked to the previous one, forming a chain of blocks. The decentralized nature Continue Reading »

Himalaya is experiencing unprecedented warming since recent past which is more than the global average and also more than the Indian sub continental landmass. The warming is even more pronounced at higher altitudes in Himalaya. This rising rate of warming at higher altitudes has been termed as Elevation Dependent Warming or EDW by the scientists working in the domain. The 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 »

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 »
