Process analysis, observations and modelling - Integrated solutions for cleaner air for Delhi (PROMOTE) Air pollution has been widely recognized as a major global health risk. Given that 1 in every 10 total deaths can be attributed to air pollution (World Bank 2016), there are major implications for the cities of the world.
As part of the Indo-Gangetic Plain (IGP), Delhi is subject to air pollution from a complex mixture of sources. As a consequence of the complex emissions and meteorology of the region, particulate matter (PM as PM10 and PM2.5), nitrogen oxides (NOx, NO2), sulphur dioxide (SO2), carbon monoxide (CO) and black carbon (BC) all peak during post-monsoon periods and remain elevated during winter making the National Capital Region (NCR) one of the most polluted areas.
Open questions remain regarding the inability of models to accurately predict air pollution during winter time fog events and quantifying incoming air pollution from large distances into Delhi. Over 4 years, PROMOTE aims to reduce uncertainties in air quality prediction and forecasting for Delhi by undertaking process orientated observational and modelling analyses and to derive the most effective mitigation solutions for reducing air pollution over the urban and surrounding region.
PROMOTE brings together a cross-disciplinary team of leading researchers from India and the UK to deliver the project aims. Its investigations will address three key questions:
- What contribution is made by aerosols to the air pollution burden in Delhi?
- How does the lower atmospheric boundary layer affect the long range transport of air pollution incoming into Delhi?
- What are the most effective emission controls for mitigation interventions that will lead to significant reductions in air pollution and exposure levels over Delhi and the wider National Capital Region?
