A study of land cover and land surface temperature changes triggered by tropical cyclone "Titli".

The intensity and frequency of tropical cyclones (TC) are on the rise due to climate change, resulting in severe damage to coastal regions. Hence, the mitigation of socioeconomic and environmental consequences of cyclones has attained paramount importance in the recent years. In this study, the rapid impact of a very severe cyclonic storm "Titli" on land cover (LC) changes were evaluated using Moderate Resolution Imaging Spectroradiometer (MODIS) and high-resolution Sentinel-2 data.

A systematic method of estimation of alongshore windstress and Ekman transport associated with coastal upwelling.

A standard method for estimating alongshore windstress (AWS) and related cross-shore Ekman transport (ET) is proposed. In the absence of standard methodologies for estimating coastal angles required for AWS estimation, an estimation is typically derived on a case-to-case basis, often approximating entire coastlines with a single line segment. A novel standard parametric method for estimating this coastal angle is developed in this manuscript consisting:•Computation of Coastal Angle from Global Self-consistent Hierarchical High-resolution Shoreline (GSHHS) coastline data through line simplification•Estimation of Windstress components at coastal points from Copernicus Marine Environment Monitoring Service (CMEMS) wind data•Estimation of AWS and associated Ekman TransportThe method developed was demonstrated for the eastern and western coasts of India.

COVID-19 lockdowns induced land surface temperature variability in mega urban agglomerations in India.

The COVID-19 pandemic forced a nationwide lockdown in India for months when close to 1.3 billion people were confined to their homes. An abrupt halt in the majority of the urban activities reduced the generation of anthropogenic heat which often exacerbates the Urban Heat Island (UHI) effect in the urban pockets of the country.

Rapid urbanization and associated impacts on land surface temperature changes over Bhubaneswar Urban District, India.

Urban settlements are the socio-economic drivers of human community. However, rapid urban expansion during recent times has a profound effect on regional as well as global rise in temperatures. Remote sensing is a powerful tool to monitor and quantify the expansion of urban built-up area and assess its effects on regional heating.
