The IIST climate Observatory is primarily beneath the cloud layer influenced by the south-west and north-east monsoonal flows, serves as a natural laboratory for conducting high quality measurements of aerosol and cloud for an improved representation of aerosol-cloud interaction in climate models. A range of field instruments has been commissioned to measure aerosol and cloud microphysics, along with meteorological variables. Following rigorous quality checks, the data collected from these instruments can be disseminated to collaborating institutions, as well as national and international users, for climate studies. The observatory is also equipped balloon launch facility for research in space science and technological demonstration.
