Monitoring inland water is crucial for assessing different aspects of the hydrological cycle, as well as environmental and atmospheric processes within the Earth system. Understanding hydrological processes and managing water resources and ecosystem balance depend greatly on tracking changes in water levels. Traditionally, water levels have been observed using in-situ gauging stations; however, the global network of these stations is 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 »
