Average echo power<strong>and</strong> signal-to-noise r<strong>at</strong>io fortropospheric soundings usingthe Davis VHF <strong>radar</strong>.Davis St<strong>at</strong>ion Research FacilityThe VHF Radar is loc<strong>at</strong>ed on the shoreline of Heidemann Bay some 2 km from Davis st<strong>at</strong>ion,Antarctica (78.0°E, 68.6°S geographic; 74.6°S magnetic). The Australian Antarctic Division<strong>and</strong> the Australian physics community have developed Davis as their primary site for highl<strong>at</strong>itudemiddle <strong>and</strong> upper <strong><strong>at</strong>mospheric</strong> physics research. Finally, the science objectives will beaddressed using the suite of instruments <strong>at</strong> Davis coupled with intern<strong>at</strong>ional collabor<strong>at</strong>ion.Middle <strong><strong>at</strong>mospheric</strong> experiments include:Rayleigh <strong>and</strong> Doppler lidar; 2 MHz Medium Frequency Spaced Antenna <strong>radar</strong>; Czerny-Turner Spectrometer observing OH airglow; Fast Fourier Transform Spectrometer observingOH airglow; Scanning Radiometer; <strong>and</strong> UV Spectrophotometer.Upper <strong><strong>at</strong>mospheric</strong> experiments include:Fabry-Perot Spectrometer; Digital Portable Sounder; Three Field Photometer; Wide AngleTwo Field Photometer; Fluxg<strong>at</strong>e Magnetometer; Induction Magnetometer; IRIS ImagingRiometer; 30 MHz St<strong>and</strong>ard Riometer; All Sky Video Camera; Ionospheric Scintill<strong>at</strong>ions;Total Electron Content; <strong>and</strong> Magnetic Absolutes.AcknowledgmentsWe acknowledge the support of the Australian N<strong>at</strong>ional Antarctic Research Expeditions (ANARE)expeditioners <strong>at</strong> Davis during the 2002-03 austral summer. The VHF <strong>radar</strong> was installed by Space <strong>and</strong>Atmosphere Science expeditioners – Damian Murphy, Ray Morris, Lloyd Symons, Danny R<strong>at</strong>cliffe<strong>and</strong> Richard Groncki, <strong>and</strong> Trade expeditioners – Paul Saxby, Alan Taylor <strong>and</strong> Chris He<strong>at</strong>h, under thesupervision of Janine Lea. Richard Groncki provided the photograph of the VHF <strong>radar</strong> <strong>at</strong> Davis.
