Chemical transport modelling and climate impacts from carbonaceous aerosols over India using WRF-CMAQ

Climate
change is influenced by short lived climate pollutants, including pollution
particles or aerosols, such as black carbon (BC), organic carbon (OC) and
“brown carbon” (BrC), in addition to greenhouse gases. We have developed emissions
inventories for India, which establish traditional biomass technologies, used
in residential and brick production sectors, and diesel vehicles, as major emitters
of carbonaceous aerosols, with important emissions from open burning of waste
and agricultural residues. In this work, the climate impact of such sectors and
technologies will be modelled using WRF-CMAQ (a regional climate model - www.cmascenter.org/cmaq/). Ongoing
field measurements of emissions particle properties from these sources, in a
related project, will be used to fine-tune optical properties used in the model.  Emissions of carbonaceous aerosols for
present day and future scenarios, will be used, to simulate radiative forcing, changes
in circulation and temperature, the urban heat-island effect, and frequency of
heat wave occurrence, over India. Mitigation strategies for achieving rapid reduction
in climate change impacts on regional scales will be developed and evaluated.
