You don’t have to live in the U.S. Midwest to have heard about the polar vortex, but if you do you’ve no doubt felt its effects. Frigid temperatures are swallowing up many states thanks to a mass of arctic air making its way much farther south than it normally does, and NASA caught a glimpse of it using one of its trusty satellites.
The Aqua satellite, launched way back in 2002, is equipped with an instrument called the Atmospheric Infrared Sounder (AIRS for short) and it’s capable of producing detailed heat maps over a huge geographical area. NASA used this tool to monitor the change in temperature created by the polar vortex.
