Questions abound about conditions in the Arctic and its role in regulating Earth\u2019s climate. Now, a UW\u2013Madison-led research program aims to answer some of those questions by developing and testing a new kind of sensor designed to fly onboard small satellites known as\u00a0CubeSats<\/a>.<\/span><\/p>\n

The\u00a0Polar Radiant Energy in the Far Infrared Experiment<\/a>\u00a0(PREFIRE) will collect data in a rarely observed part of the energy spectrum, giving new insight into Arctic warming, sea ice loss, ice sheet melt and sea level rise.<\/span><\/p>\n

\u201cThe Arctic is Earth\u2019s thermostat,\u201d says\u00a0Tristan L\u2019Ecuyer<\/a>, UW\u2013Madison professor of atmospheric and oceanic sciences and principal investigator for the PREFIRE science mission. \u201cIt regulates the climate by venting excess energy received in the tropics, and this data will fill a major gap in our knowledge about the Arctic energy budget.\u201d<\/span><\/p>\n

Nearly 60 percent of Arctic emission occurs at wavelengths that have never been systematically measured in the far infrared until now, says L\u2019Ecuyer. Recent innovations in detector miniaturization at NASA\u2019s Jet Propulsion Laboratory have enabled, for the first time, the collection of these measurements onboard the relatively tiny CubeSats, which are only slightly larger than a loaf of bread.<\/span><\/p>\n

For PREFIRE, two CubeSats, placed in a low altitude polar orbit, are expected to launch in 2021. Each satellite will collect data for one year over the Earth\u2019s Arctic regions, and data from the experiment will be received and processed by the UW\u2013Madison\u00a0Space Science and Engineering Center<\/a>\u00a0and later archived by NASA.<\/span><\/p>\n

\u201cWhen integrated into today\u2019s climate models, the new data from this experiment will improve our ability to understand our changing climate and predict how fast Arctic snow and ice will melt,\u201d says L\u2019Ecuyer.<\/span><\/p>\n

The $35 million PREFIRE project is funded through a NASA Earth Venture-Instrument grant. In addition to NASA and UW\u2013Madison, other partners include Utah State University Space Dynamics Laboratory, the University of Michigan and the University of Colorado Boulder.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
