Real-time apportionment study up and running again in Delhi
Hindustan TimesThe Delhi government’s real-time source apportionment study has been operationalised, with real-time data on the sources of pollution from PM2.5 particulates impacting the Capital now available on the R-asmaan portal, officials aware of the matter said. The apportionment study looks at nine sources of PM2.5 particulates — secondary inorganic aerosols, road dust, vehicles, industries, construction, biomass burning, coal and fly ash, waste burning, and pollution from the residential sector. On Wednesday, a senior DPCC official said the site of the apportionment study at Rouse Avenue was made operational the day after the Supreme Court’s orders, with real-time data reflecting on the website from the last couple of days. The apportionment study is different from the Decision Support System, under the Union ministry of earth sciences, which is an estimate-based model that estimating the sources contributing to Delhi’s PM 2.5 levels using meteorological conditions and a long-term emissions inventory from each sector.
