Delhi Air Quality Plummets in October Start
2 Oct
Summary
- Delhi's air quality declined to a 'moderate' AQI of 166 on October 1st.
- PM10 was the primary pollutant, with weakening rainfall dispersion effects.
- Neighboring NCR cities also experienced similar air quality declines.
The air quality in Delhi significantly deteriorated on October 1st, marking the lowest air quality index (AQI) in the past week with a 'moderate' reading of 166. This marks a decline from the previous day's 'satisfactory' AQI. Particulate matter (PM10) was identified as the dominant pollutant, with experts noting that the weakening effects of recent rainfall contributed to this dip.
This seasonal air quality slump is attributed to the upcoming festival season and accelerated harvest activities, which will reduce atmospheric dispersion. Experts emphasize the need for long-term solutions to abate baseline emissions from various sectors to prevent the inevitable decline in air quality. Neighboring cities in the National Capital Region (NCR), including Noida and Ghaziabad, also reported similar air quality issues.
Meanwhile, temperatures in Delhi began to rise, with the minimum temperature at 24°C and the maximum at 35.2°C, both slightly above normal. The India Meteorological Department (IMD) forecasts a continuation of dry weather for the next few days, with a potential for isolated rainfall around October 6-7 due to a western disturbance.
Despite the rising temperatures, the IMD does not anticipate heatwave conditions. The expected rainfall around October 6-7 could bring another change in weather, offering a temporary respite from the dry spell and warmer conditions. This period might also see rainfall in other parts of northwest India.
