POLES
Definition
- The Polar Exchange at the Sea Surface (POLES) is an EOS interdisciplinary project investigating the exchange of mass and energy at the air-ice-ocean interface in the polar regions. POLES is a broad investigation into the role of polar regions in the global energy and water cycles, and the atmospheric, oceanic and sea ice processes that determine that role. The primary importance of investigation is to show how these polar processes relate to global climate. The POLES program is located at the Polar Science Center, Applied Physics Laboratory, University of Washington. The primary goal of the Earth Observing System (EOS), a program of the National Aeronautics and Space Administration (NASA), is to advance the scientific understanding of the entire Earth system. Scientists from 8 disciplines and 4 institutions have joined together in the POLES investigation to use the rich array of satellite data collected from the polar regions. The data have been collected using a variety of satellite-based sensors, including passive microwave radiometers, the TIROS-N Operational Vertical Sounder (TOVS), Advanced Very High Resolution Radiometer (AVHRR), and synthetic aperture radar (SAR). POLES scientists use satellite data to build an understanding of long-term patterns in the fluxes of heat, moisture, and momentum across the surface of the polar oceans. Their goal is to assimilate satellite (and some buoy) observations into polar ocean-atmosphere models that not only refine the treatment of surface exchange processes, but also quantify the roles of horizontal transports, oceanic mixing, and deep convection. With better use of data, researchers can move beyond present climatological descriptions and document interannual variability.
