Delhi Air Quality News

Diwali in Delhi began with a “very terrible” start. “According to officials, air quality is expected to deteriorate regardless of cracker bursting. The capital’s air quality index (AQI) was 341 at 8 a.m., up from 314 at 4 p.m. on Wednesday. On Tuesday, the 24-hour average AQI was 303, up from 281 on Monday.
The AQI between zero and 50 is regarded as ‘good,’ 51-100’satisfactory,’ 101-200’moderate,’ 201-300 ‘poor,’ 301-400’very poor,’ and 401-500’severe.’ While SAFAR stated that the air quality might become severe on November 5 and 6 if firecrackers are set off, an official from the India Meteorological Department said that model estimates do not show the AQI reaching the severe level “even with greater emissions.” “..
According to the ministry of earth sciences’ air quality forecast agency, 3,271 farm fires accounted for 8% of Delhi’s PM2.5 pollution on Wednesday. According to the forecast, it is expected to rise to 20% on Thursday (Diwali) and then to 35-40% on Friday and Saturday as the wind shifts to the northwest.
Smoke from farm fires in Punjab and Haryana is carried to the national capital by northwesterly winds. Last year, on November 5, the amount of stubble burning in Delhi’s pollution peaked at 42%. On November 1, 2019, agricultural residue burning accounted for 44% of Delhi’s PM2.5 pollution.
Gopal Rai, the Delhi environment minister, urged the Centre on Wednesday to send advice to Punjab, Haryana, and Uttar Pradesh to entirely halt stubble burning during the Diwali season so that people may breathe more accessible after the festival. The contribution of stubble burning to Delhi’s PM2.5 concentration on Diwali day last year was 32%, compared to 19% in 2019.
Due to the record-breaking rainfall in October and “unfavorable” weather conditions, farm fires’ impact on Delhi’s air pollution has stayed low this season. “Wind direction for smoke transport from stubble burning. “Very calm,” warned SAFAR. “For the next three days, local Delhi wind conditions with limited ventilation are forecast, which will be unfavorable for pollutant dispersion.
