This is the second paper of a series devoted to atmospheric optical turbulence Cn2 observation using a mobile polar atmospheric parameter measurement system.We present the initial results of Cn2 measurement at Antarctic Taishan Station using micro-thermal sensors and a three-dimensional sonic anemometer at height~2.0 m above the snow surface.The site testing experiments were carried out during the 30th Chinese National Antarctic Research Expedition(CHINARE).We collected about 1 000 h of data between 30 December 2013 and 10 February 2014.The Cn2 curve exhibits clear daily structures,with two peaks around midnight and midday and two troughs around 7:30 and 17:00 local time(UTC+5).The mean Cn2 is 2.7×10?15 m?2/3 and the 25th and 75th percentiles of the Cn2 cumulative distribution are 9.6×10?16 m?2/3 and 6.2×10?15 m?2/3,respectively.Meteorological parameters such as temperature,relative humidity,wind speed,and air pressure are also presented.
