Arctic Observing eXperiment

Our ability to understand and predict weather and climate requires an accurate observing network. One of the pillars of this network is the observation of the fundamental meteorological parameters: temperature, air pressure, and wind. We plan to assess our ability to measure these parameters for the Polar Regions during the Arctic Observing Experiment (AOX) to support the International Arctic Buoy Programme (IABP), the Arctic Observing Network (AON), the International Program for Antarctic Buoys (IPAB), the BRomine Ozone and Mercury EXperiment (BROMEX), and the Southern Ocean Observing System (SOOS). For example, such parameters are crucial for the Rising Air Parcel Model assimilation to characterize the dynamics and transport of tropospheric bromine that impacts ozone depletion and mercury deposition in the Arctic environment. Accurate temperature measurements are also necessary to validate and improve satellite measurements of surface temperature across the Arctic. Support for research associated with the campaign is provided by the National Science Foundation.
