The height of the atmospheric boundary layer on the Antarctic plateau is of particular interest to meteorologists and designers of optical telescopes for Antarctica. “Snodar” was developed at the University of New South Wales to measure the height of the boundary layer at Dome A and Dome C on the Antarctic plateau. Snodar operates between 3 kHz and 14 kHz and has a vertical resolution of 1 m or better. Snodar was deployed to Dome A in 2008 and was found to have sufficient sensitivity to be able to measure the height of the atmospheric boundary layer with a single pulse. We present here the technical details of a second-generation Snodar, which will be deployed to Dome A in 2009. 1.
