A study is carried out to identify the active forest fire in Uttarakahd state during April-May, 2024 using satellite images. A satellite image captures the response of the electromagnetic spectrum by various land features.  The spectral signature of forest fire spectral indicates that it has the highest reflectance in the Short Wave Infrared wavelength and at the same time there Continue Reading »

Manu Mehta and Akhilesh Kumar Estimating atmospheric aerosol levels is crucial for accurate radiative forcing calculations, understanding aerosol effects on cloud formation, assessing human health impacts, and planning pollution control. Continuous monitoring of aerosols in both space and time is essential to understand its effects in human life. Ground-based networks like AERONET and ARFINET use instruments such as sun-photometers and Continue Reading »

Kshama Gupta and Kakali Deka An international study highlights the significant role of climate change in the record-breaking heatwave affecting Asia, including India. India is facing early and severe heatwaves for the third consecutive summer, with temperatures already reaching 48°C in many Indian States and expected to hit 50°C. The India Meteorological Department (IMD) reports that 2022 was the fifth 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 »

As India struggles with intense heatwaves striking earlier than usual for the third consecutive summer, millions are facing the dual challenges of stifling humidity and soaring temperatures. This concerning trend, exacerbated by the effects of climate change, poses significant threats to public health, emphasizing the critical need for adaptive measures. Researchers caution that without prompt intervention, the lives of over Continue Reading »
