MF radar observations of antarctic mesosphere and lower thermosphere

The observations of middle atmosphere have been conducted mainly in mid-latitudes so far, although global scale observations are required for the study of the middle atmosphere. We are planning to construct an MF radar observatory at Syowa Station, Antarctica (69°S, 39°E) in 1999. The MF radar obser...

Description
Summary:The observations of middle atmosphere have been conducted mainly in mid-latitudes so far, although global scale observations are required for the study of the middle atmosphere. We are planning to construct an MF radar observatory at Syowa Station, Antarctica (69°S, 39°E) in 1999. The MF radar observations of horizontal neutral wind velocity (60-100km) are characterized by its high time-height resolutions of 2min-4km and the continuous operation throughout a day, which enables us to observe various atmospheric phenomena over wide frequency range from gravity waves to planetary waves. Further, we discuss the importance of combined observations with other measurement techniques like Na lidar, FPI, all-sky imager and HF radar, and also international cooperative studies through global atmospheric radar networks.
