Summary
This paper presents the meteor temperatures estimated using two radars installed in Davis (69 deg S, 78 deg E), Antarctica. The Davis MST radar was installed in February 2003, primarily for observation of polar mesosphere summer echoes, with additional transmit and receive antennas installed to allow all-sky interferometric meteor radar observations. The Davis meteor radar was installed in January 2005, and also allows all-sky interferometric meteor radar observations. Meteor temperatures are estimated using two techniques: pressure model and temperature gradient model. The temperatures are compared with a temperature model derived using co-located OH spectrometer measurements and northern Hemisphere rocket observations. Pressure model temperatures derived using rocket derived pressures show good agreement with the temperature model, while those derived using MSIS and CIRA model pressures show good agreement in winter but poor agreement in summer. Meteor echoes observed simultaneously by the MST and meteor radars are used to estimate the accuracy of meteor various parameters, leading to improved meteor temperature estimates.
