This is the second paper of a series devoted to atmospheric optical turbulence C n 2 observation using a mobile polar atmospheric parameter measurement system. We present the initial results of C n 2 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 C n 2 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 C n 2 is 2.7×10 -15 m -2/3 and the 25th and 75th percentiles of the C n 2 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. Citation: Tian Q G, Jiang P, Wu X Q, et al.
