Today’s Image of the Day from NASA Earth Observatory features waves of dust over northern China during a sandstorm on December 12, 2022.
“Airborne particulate matter from the storm created hazardous air conditions in Beijing and surrounding areas. At the U.S. Embassy in Beijing, the air quality index for fine particulate matter (PM2.5) exceeded 300, which is considered hazardous to human health,” says NASA.
“Air quality measurements by the Beijing Environmental Protection Monitoring Center for PM10 (larger dust particles) reached 999 – the maximum threshold for the indicator. Beijing residents were warned to stay inside, according to news reports.”
