Unique phenomena and structure of the polar atmosphere
The frontiers of atmospheric science
PANSY probes polar phenomena and their physics
The PANSY radar first successfully conducted observations in March 2011,
and since April 2012, has been making continuous obsrevations of the troposphere, stratosphere and mesosphere
Syowa Station is an important station where many kinds of regular atmospheric observations are performed by several organization including Japan Meteorological Agency and National Institute of Polar Research. Anthropogenic signals are well detected in the Antarctic atmosphere, which is isolated from human activities. In addition, many kinds of distinct and unique atmospheric phenomena such as katabatic wind, ozone hole, polar mesospheric cloud, and aurora are observed there. Japanese Antarctic Research Expedition exceeded 50 years and is being to transfer from discovering and environment-monitoring observations to precisive observations in which quantitative evaluations of atmospheric processes are possible. Based on these backgrounds, our project aims to pass the limit of current atmospheric science by combining the PANSY radar installed at Syowa Station, which can observe the height region from the troposphere to the ionosphere with high temporal and vertical resolution, many pre-installed observations at Syowa Station, and high-resolution climate models.
The PANSY radar started its construction in Dec. 2010 as the first MST/IS radar in the Antarctic and succeeded in the detection of the first echo from the Antarctic atmosphere in March 2011.
The PANSY radar started tropo/stratosphere observations from April 2012 with 12/55 of a full array system (i.e., 228 antennas).
The PANSY radar performed PMSE（Polar Mesosphere Summer Echo）observations in January-February 2012 with 1/55 of a full array system (i.e., 19 antennas).
