Exposure modelling for air pollution in India: Challenges and opportunities

摘要: BACKGROUND AND AIM Our consortium of exposure scientists and health researchers –CHAIR-India is developing a nation-wide exposure model for particulate matter. Our aim is to build a comprehensive database which will help develop/validate a hybrid exposure model. In this process, we attempt to discuss the gaps and indicate potential solutions to improve air pollution monitoring data quality. METHODS Data was collected from online monitors from Central Pollution Control Board (CPCB) Continuous Ambient Air Quality Monitoring Stations (CAAQMS) as well as offline monitors as part of the National Ambient Air Quality Monitoring Programme (NAMP) between the years of 2005-2020. Variables assessed were unique station name/ID, dates, pollutant variables – (PM2.5, PM10), geographical information (lat/long) and type of PM data generated (Gravimetric/BAMS). These data were collated, sorted and …
