Thick smog over eastern China • Earth.com

Today’s Image of the Day comes from the NASA Earth Observatory and features a look at a thick layer of smog in the skies over eastern China.

This type of smog is often caused by temperature inversions. Normally, air cools as it rises in altitude,  but during an inversion, a pocket of warm air sits on top of the cool air and traps pollutants from escaping.

This image was captured by the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi NPP satellite.
