Rain clears smog in Indian capital yet air quality 'very poor'

Jan 6, 2019 7:00 AM

NEW DELHI (Reuters) - A rainy spell early on Sunday brought better air to residents of New Delhi, giving them a brief respite from thick grey smog that has shrouded the Indian capital for the last two months, although air quality continued to be “very poor”.

A measure of tiny, hazardous breathable particles known as PM 2.5 reached an average of 182 by 12 p.m., the Central Pollution Control Board said, its lowest since Nov. 4.

But pollution was still five times more than a U.S. government recommended level of 35 to stand at “unhealthy” levels, according to the U.S. embassy.

“Change in weather conditions by rain or higher wind speed helps dissipate peak pollution, but we continue to need strong emergency actions such as shutting power plants,” said Anumita Roychowdhury of the Centre for Science and Environment think-tank.

The federal government air quality index rated Delhi’s air quality “very poor” on Sunday and had a similar forecast for Monday, urging people with respiratory and cardiac problems to avoid polluted areas and limit outdoor movement.

A sharp drop in temperatures and wind speed over the last two weeks, combined with vehicle and industrial emissions, dust from building sites and smoke from garbage burning has stoked pollution over much of north India.

Levels of PM 2.5, or particles smaller than 2.5 microns in diameter, hit their highest last year at 450 on Dec. 23.

Despite the pollution, there is little sign Delhi’s 20 million residents are taking steps to protect themselves. Activists say the apparent lack of concern gives politicians the cover they need for not tackling the issue adequately.

Spent some time today to superimpose two screen shots otherwise I get flooded with each guy asking about weather for his destination
For Spiti:

10th is perfect day to hit the road. If you plan to reach Kaza on 12 then you will be in time for the snowfall. This prediction is for later part of the day on 12th January 2019.
if you can head out on 9th that will be even better cause when you wake up on 12 th you will see the system move in and also witness the surroundings change from brown to white.....
