Runway Visual Ranges (RVRs) now range from 400 to 800 metres, indicating improved aviation conditions.
The Centre on Saturday removed stringent curbs, including a ban on construction work related to linear projects and the entry of polluting trucks into Delhi, in view of the dip in air pollution levels
It also found that 67.4 per cent of the country's population lives in areas that exceed the country's own national air quality standard of 40 g/m3.
At least 146 firefighters, the Navy and the Air Force helped douse the fire at the waste dump yard. Per minute, 60,000 litres were pumped.
Analysis of days as per AQI categorisation showed that Kochi city has not been able to sustain the air quality gains of 2020.
Experts attributed this to the shifting of the peak stubble burning period by around a week due to a prolonged monsoon season.
The high pollution levels are likely to impact more people this year as a significant proportion of people who recovered from COVID-19 might not have completely healthy lungs.
A bench headed by NGT Chairperson Justice Adarsh Kumar Goel clarified that the direction will apply to all cities and towns in the country where the average of ambient air quality during November 2019 was in 'poor' and above categories.
As China moves past the peak of its crisis, however, recent images by the European Space Agency show a resurgence in NO2 emissions.
On Sunday, pollution level in Delhi peaked to a three-year high as high humidity due to light rains on Saturday led to formation of more potent secondary particles.
