Dr. Dilip Ganguly is a Professor in the Centre for Atmospheric Sciences, Indian Institute of Technology (IIT) Delhi, Hauz Khas, New Delhi, India.
Dr. Ganguly received his Bachelors degree in Physics from University of Calcutta in 1999. He then moved to Banaras Hindu University and received a degree in Master of Science in Physics in 2001. He went to Physical Research Laboratory (PRL) in Ahmedabad, India as a research scholar to complete his PhD in June 2006 (degree was awarded by Gujarat University in Jan 2007). Following his PhD, he remained at PRL as a Postdoctoral Research Fellow until June 2007. Subsequently in July 2007, he joined as a Postdoctoral Research Associate in the Atmospheric and Oceanic Sciences Program at Princeton University, Princeton, NJ, USA and worked as a Visiting Scientist at NOAA Geophysical Fluid Dynamics Laboratory, Princeton, NJ, USA. In June 2010, he moved to Richland, WA to work as a Research Scientist at Pacific Northwest National Laboratory (PNNL). Dr. Ganguly returned back to India in September 2012 to work as a Visiting Scientist at Indian Institute of Tropical Meteorology, Pune. In February 2013, he joined IIT Delhi as an Assistant Professor in the Centre for Atmospheric Sciences.
Dr. Ganguly’s broad research interest is to investigate the role of aerosols in the climate change mechanism through their influence on the radiative transfer of the atmosphere and cloud microphysical processes. This involves estimation of direct and indirect radiative forcing of aerosols across the globe in terms of contribution from major aerosol species such as black carbons, organics, sulfates etc. The tool that he is currently using is climate modeling. He has expertise in modeling the production, transport, transformation, and removal of atmospheric aerosols in General Circulation Models like AM2, AM3 and CAM5. He extensively uses remote sensing data from satellites as well as in-situ data from measurements across the world to validate the model results. During his graduate studies, he also carried out laboratory measurements of aerosols and participated in many field campaigns. He collaborated with various scientists from NOAA, NASA and elsewhere to develop an original method to infer the composition and concentration of aerosols by combining sun-photometer and Lidar data. This method is very useful for model validation because it provides data that can be used to validate directly model results, rather than derived quantities (e.g. aerosol optical depth). He has a special interest in improving our present understanding regarding the role of aerosols in modulating the Indian summer monsoon system. Dr. Ganguly’s research article on this subject “Climate response of the South Asian monsoon system to anthropogenic aerosols” published in JGR was also highlighted in Nature as the community choice article: "Aerosols Keep Down Monsoon Rain". Dr. Ganguly wants to continue his contribution towards the improvement of treatment of aerosols in climate models such that they are able to better reproduce the present climate and hence can be used to make reliable projections of future climate.
