Research led by Professor Ranjeet Sokhi, director of the Centre for Atmospheric and Instrumentation Research, has developed novel high-resolution air quality models for urban areas. These models can calculate pollutant concentrations in different parts of a city and at different times of day in order to estimate the exposure to pollution experienced by the local population - and allow local authorities to introduce effective mitigation measures.
City authorities in Bristol and Greater Manchester attribute the premature death of approximately 200 and 1300 people annually to poor air quality.
Funded by the Natural Environment Research Council, the High Resolution Forecasting of Air Quality and Exposure for Healthier Cities (HiRAE) project, led by University of Hertfordshire, brought air quality and population exposure forecasts down to the street scale, whilst making all the data available to local authorities for the first time.
Delhi is one of the most polluted cities in the world; pollution levels peak during post-monsoon periods and remain elevated during winter. Existing models cannot accurately predict air pollution during winter time fog events or quantify incoming pollutants from coming into Delhi from outside the city.
Over four years the PROMOTE project - Process analysis, observations and modelling: integrated solutions for cleaner air for Delhi - aims to reduce uncertainties in air quality prediction and forecasting for Delhi by carrying out new modelling analyses to derive the most effective mitigation measures.
The Environment Food and Rural Affairs, Environmental Audit Committee, Health, and Transport Committees are holding a joint inquiry on air quality to scrutinise cross-government plans to tackle pollution hotspots.
