Low temperature Antarctic Automatic Weather Stations

During the International Polar Year (IPY, 2007-2009), several ground traverses penetrated the remote interior plateau of East Antarctica to search (among other things) for the oldest ice chronology on Earth. One of those traverses connected the Norwegian Troll station to Amundsen-Scott South Pole station, via the former Plateau station and the pole of inaccessibility. This offered a unique opportunity to extend the present operational area of IMAU AWS to the deep interior ice sheet. In this project we designed and build two AWS with low temperature specifications for installation along this IPY traverse, and one prototype for testing at Kohnen station. We installed these AWS at the site of former Plateau station and on the interior slope of west Dronning Maud Land, an area that is meteorologically unexplored. The AWS will be left unattended for a period of 3-5 years, relaying their data to Utrecht through the ARGOS system.
