A Look At Delhi Weather, Air Pollution After Monday's Rain

New Delhi: Overnight rain on Monday night improved the air quality and gave Delhi some respite from severe air pollution. The Indian Metrological Department (IMD) said that Delhi is expected to witness more spells of light to moderate rain and it will help to bring the pollution levels further down. The MeT department has also predicted moderate to dense fog in the next few days.

Major pollutant PM 2.5, or pollution particles in air with diameter less than 2.5 micrometers, across 22 areas of Delhi-NCR dropped from 249 units at 5 pm (before the drizzle) to 248 units at 6 pm (after the drizzle).

On Monday, the Air Quality Index in Ghaziabad (463) and Noida (408) was "severe", according to Central Pollution Control Board (CPCB).

The air quality was described as "severe plus" at Anand Vihar (PM2.5 reading 431) in east Delhi on Monday, but after showers, the PM 2.5 was 124 at 7 pm on Tuesday.

At Delhi Technical University PM2.5 was 428 in north Delhi, but post showers, the reading showed PM 2.5 as 145 on Tuesday at 7 pm.

At RK Puram in south Delhi PM2.5 recorded at 270 on Monday, but the next day, the concentration was 90.

At Mandir Marg in central Delhi, the air quality was severe with PM2.5 recorded as 261 units and on Tuesday 7 pm, it showed PM 2.5 as 92, as per Central Pollution Control Board.

The safe limit for PM2.5, according to international standards, is 25 microgrammes per cubic metre and 60 as per national standards.
