Study finds COVID-19 lockdown in China brought only slight reduction in PM2.5 and ozone

Green Car Congress

Large improvements of air quality in China during the lockdown have been widely reported, but new research shows that two pollutants harmful to human health—fine particulate matter (PM 2.5 ) and ozone—were only slightly reduced. and ozone were only slightly reduced or barely affected.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Researchers identify four new man-made gases contributing to destruction of ozone layer

Green Car Congress

A study by an international team led by scientists at the University of East Anglia have identified four new man-made gases in the atmosphere, all of which are contributing to the destruction of the ozone layer. CFCs are the main cause of the hole in the ozone layer over Antarctica. —Lead researcher Dr. Johannes Laube.
