TitleInertia-gravity waves in Antarctica: A case study using simultaneous lidar and radar measurements at McMurdo/Scott Base (77.8 deg S, 166.7 deg E)AbstractThis study presents the first coincident observation of inertia-gravity waves (IGWs) by lidar and radar in the Antarctic mesopause region. This is also the first known observation of two simultaneous IGWs at the same location. An Fe Boltzmann lidar at Arrival Heights (77.8 deg S, 166.7 deg E) provides high-resolution temperature data, and a co-located MF radar provides wind data. On 29 June 2011, coherent wave structures are observed in both the Fe lidar temperature and MF radar winds. Two dominant waves are determined from the temperature data with apparent periods of 7.7 +- 0.2 and 5.0 +- 0.1 h and verticalAcknowledgementsWe sincerely acknowledge Wentao Huang, Zhangjun Wang, John A. Smith, Brendan Roberts, and Chester S. Gardnerfor their significant contributions to the McMurdo lidar campaign. Weare grateful to Anne Smith, Han-Li Liu, and Mike Nicolls for valuablediscussions. We appreciate the staff of McMurdo Station and Scott Base for their superb support. We offer special thanks to Ed Butler of the Antarctica New Zealand and Vladimir Papitashvili of the National Science Foundation for their encouragement and help in this collaborative research.The lidar project is supported by the USA National Science FoundationOPP grant ANT-0839091. AJM thanks Antarctica New Zealand for thelogistic support for the MF radar. SLV is supported by NSF grant AGS-1139149.
