INteraction of Convective Organization and Monsoon Precipitation, Atmosphere, Surface and Sea (INCOMPASS)

We are currently participating in an Indo-UK bilateral project on South-Asian Monsoon, jointly funded by Ministry of Earth Sciences (MoES) and Natural Environment Research Council (NERC), UK. This multi-institutional project headed by Indian Institute of Science, Bangalore has collaborators from several institutes including IIT, Kanpur (IITK) and seeks to improve the skill of rainfall prediction in operational weather and climate models by way of better understanding and representation of interactions between the land surface, boundary layer, convection, the large-scale environment and monsoon variability on a range of scales. IITK is the supersite where a lot of instruments have been deployed for the campaign. Already working eddy covariance flux tower is measuring land to atmosphere energy and carbon fluxes. Simultaneously, remote sensing of aerosol vertical profile, cloud height and coverage, wind profile, temperature and humidity profile, along with surface measurements of aerosol physical, optical and microphysical properties are being made. Recently, radiosondes were launched from IITK to support the remote sensing instruments. This site will provide support to the intermittent aircraft measurements over Indo Gangetic Plains (IGP).

We conduct laboratory experiments of aerosols to quantify their spectral absorption, hygroscopic and microphysical properties. We also formulate various modeling tools to improve process-level understanding (e.g. role of mixing state, brown carbon) of these properties including new particle formation.

In addition, we are conducting comprehensive analyses to improve our understanding of physical and optical properties of aerosols over the Indo-Gangetic Basin. This involves aerosol-related data from various platforms including long-term ground based and satellite, as well as intensive short- term campaign. Our ultimate goal is to accurately represent aerosol effects in the regional climate-chemistry models that are used to estimate the climate and health impacts of aerosols over the Indo-Gangetic Basin. We are also interested in the development of new techniques for measurement of aerosol absorption. 

I am also associated with  Centre for Environmental Science &  Engineering.
