With remote-sensing satellites, scientists have found the coldest places on Earth, just off a ridge in the East Antarctic Plateau. The coldest of the cold temperatures dropped to minus 135.8 F. Where is the coldest temperature ever measured on Earth?
"It's in Antarctica of course," Ted Scambos, lead scientist at the National Snow and Ice Data Center in Boulder, Colo., said here today (Dec. 9) at the annual meeting of the American Geophysical Union.
he temperature measurement came from the most detailed global surface-temperature maps made to date, which were created using data from the new Landsat 8 satellite, launched in February, and 32 years' worth of data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA's Terra and Aqua satellites and instruments aboard several other satellites.
They turned to the temperature records from the satellites, whose instruments measure the thermal radiation emitted at Earth's surface. The coldest temperature they found occurred on Aug. 10, 2010 (winter in the Southern Hemisphere). The temperature is essentially the same "as if you were to take your hand and put it on the surface of the snow. I don't recommend that, as, in this case, that would be colder than dry ice," Scambos said. It's "50 degrees colder than anything that has ever been seen in Alaska, or Siberia," he added.
