Afternoon AQI rises further to 244 in Delhi
The Hindu ↗Morning AQI reaches 238 as Stage 1 invoked
Mint ↗Citywide AQI remains moderate ahead of expected deterioration
NDTV India ↗Forecast points to six days of poor air
Times now ↗Coldest night of month recorded at 17.1 degrees Celsius
The Hindu ↗Delhi warned of season's first poor air spell
Times of India Top Stories ↗How it started
Warnings preceded the latest deterioration. On October 18, Times of India Top Stories reported that Delhi's air was expected to turn poor for the first time this season.
Cooler weather accompanied the warnings. The Hindu reported on October 19 that Delhi had recorded its coldest night of the month so far, at 17.1 degrees Celsius. The India Meteorological Department forecast mainly clear daytime skies and a maximum temperature of around 32 degrees Celsius.
How it unfolded
On October 19, Times now reported that Delhi's air quality was expected to remain poor for six days. Its coverage raised concerns about respiratory health, although the supplied report does not establish specific effects from short periods of exposure.
On October 20, the citywide reading was still moderate. NDTV India put Delhi's AQI at 179 and reported that it was expected to deteriorate into the poor category from Wednesday, October 21. Separately, Times now reported poor readings in some areas on October 20, alongside a forecast of no rain for Dussehra.
By 10 am on October 21, the AQI had reached 238, according to Mint. The outlet reported that the Commission for Air Quality Management had invoked Stage I of the Graded Response Action Plan.
The reading rose further to 244 at 2 pm, The Hindu reported, compared with 179 the previous day. The morning and afternoon figures describe different observation times, rather than conflicting accounts of the same reading.
Where it stands
Stage 1 curbs are now in effect across Delhi and the National Capital Region. Times now reported that the measures took effect on October 21 after air quality entered the poor category.
According to NDTV Top Stories, GRAP Stage 1 applies when the AQI is between 201 and 300, and parking charges are to be doubled. The latest afternoon reading of 244 places Delhi within that range.
What to watch
The next AQI readings will show whether Delhi remains in the poor category, as earlier forecasts suggested. Times now reported a six-day outlook on October 19, but the supplied coverage contains no newer forecast confirming how long the deterioration will last.
