China has been grappling with a very serious smog problem that is covering several major cities of the country. There are obvious health and visibility concerns with the smog, considering the concentration of PM2.5 fine air particulates has gone beyond the hazardous mark a couple of times. This image, captured by Moderate Resolution Imaging Spectroradiometer (MODIS) shows just how bad the situation got in Eastern China.
NASA explains:
The concentration of PM2.5, which are fine air particulates, were reported at 421 micrograms per cubic meter at 2 p.m. near Tiananmen Square in Beijing, while levels were 795 in Xi’an and 740 in Zhengzhou. The World Health Organization (WHO) recommends 24-hour exposure to PM2.5 concentrations no higher than 25 micrograms per cubic meter.
The image was taken on December 23.
