Americans throughout the Midwest and Northeast can settle on something– it’s.
truly, truly cold today— and a NASA satellite tracking air temperature levels verifies the belief.

An instrument called Atmospheric Infrared Sounder, or AIRS, on the Aqua satellite has actually been determining the temperature level of air masses throughout the United States. Aqua itself released in 2002 and brings a half lots various instruments created to study parts of the water cycle, consisting of evaporation, cloud development and rainfall.

The AIRS instrument concentrates on temperature level measurements, making it a handy tool for taking a look at today’s freezing weather condition and its cause, the so-called polar vortex phenomenon in which cold Arctic air sneaks further south than typical.

The brand-new NASA visualization of the instrument’s information reveals measurements collected in between Jan. 20 and Jan.29 Temperature levels as low as minus 40 degrees Fahrenheit (minus 40 degrees Celsius) are on display screen in purple, and can be seen extending as far south as South Dakota, Iowa and northern Illinois. Whatever in pale blue and “cooler” colors represents temperature levels listed below the freezing point of water, 32 degrees Fahrenheit (0 degrees Celsius).

If you reside in the areas presently based on this freezing air, make certain to wrap and watch on regional weather report till the cold retreats.
