Welcome to the Centre for Atmospheric and Oceanic Sciences (CAOS).

We are a centre within the Division Mechanical Sciences at the Indian Institute of Science (IISc), Bengaluru. Our research addresses a wide variety of topics within the broad realm of atmosphere-ocean-climate science. Formally, we offer graduate degrees at the Masters and Doctoral level. We are also closely associated with the Divecha Centre for Climate Change.


Research at CAOS revolves around the tropical climate. In addition to the theme of understanding the monsoon and its variability, current faculty interests span a wide range of topics in the realm of atmosphere-ocean-climate sciences.
