Unravelling Diurnal Asymmetry of Surface Temperature in Different Climate Zones

Abstract Understanding the evolution of Diurnal Temperature Range (DTR), which has contradicting global and regional trends, is crucial because it influences environmental and human health. Here, we analyse the regional evolution of DTR trend over different climatic zones in India using a non-statio...
