Title: The COALESCE Project, India: A Framework to Unravel the Air Quality and Climate Effects of Aerosols
Abstract:
This talk will commence with an overview of the Carbonaceous Aerosol Emissions, Source Apportionment and Climate Impacts (COALESCE) project, its organization, work elements and key hypotheses. The discussions will then focus on specific aspects of network design for aerosol sampling, chemical analyses, and source apportionment.
A large segment of this talk will be devoted to better understanding the nature and behavior of ambient fine particulate matter in India, using measurements made at Bhopal, central India, as an example. Bulk aerosol physio-chemical and optical characteristics, their temporal evolution and sources will be discussed. Also, the implications of COVID-19 induced lockdowns on aerosol characteristics over the study location will be outlined. Finally, snapshots of fine PM sources and their contributions across some network locations will be presented. This talk will conclude with expected outcomes of the COALESCE project and their implications for policy making.
Bio:
Ramya Sunder Raman is currently Professor, Earth and Environmental Sciences. She is also the Dean, Faculty Affairs at IISER Bhopal. In the past she has served the Institute as Dean, Academic Affairs; Head, Centre for Science and Society (CS2); Coordinator, Centre for Research on Environment and Sustainable Technologies (CREST); and the Head, Department of Earth and Environmental Sciences. Her research interests are in ambient aerosol characterization, transformations, and source-specificity of its impacts. Her group works at the interface of aerosol science/technology and atmospheric dynamics, with a focus on coupling air quality management with health and climate end-points. Their endeavour is to build capacity and tools to provide a data-centric platform to inform air quality management decisions and to support environmental justice actions. Her group is involved in several projects aimed at understanding and managing ambient aerosol induced burden on air quality over locations in India. She is currently co-leading a work-packet in the pan-India multi-institute consortium project, Carbonaceous Aerosol Emissions, Source Apportionment and Climate Impacts (COALESCE).
Prof. Sunder Raman graduated with MS and PhD degrees in Chemical Engineering working with Prof. Philip K Hopke at Clarkson University, Potsdam NY, USA. Thereafter she worked as a post-doctoral research associate at the Centre for Air Resources Engineering and Science (CARES), Clarkson University, Potsdam, NY and the Physical Research Laboratory (PRL) Ahmedabad, India before moving to a faculty position at IISER Bhopal in 2009.
