Abstract

In the present paper, stable isotope (δ18O) of air moisture is used to investigate geospatial correlation in moisture variability between two stations – Tezpur (Assam) and Roorkee (Uttarakhand). The isotopic composition of air moisture has shown a good correlation in time domain. It was found that the isotopic composition of air moisture in the monsoon period is depleted in comparison to non-monsoon period which opens up a possibility of using isotopes as a tool to track movement of monsoon vapours.
