摘要
研制了移动式极地大气参数测量系统。采用温度脉动仪和三维超声风速计分别对大气湍流强度C2n进行测量。在合肥和上海两地进行了约500 h的仪器性能测试,结果显示仪器运行稳定、两种方法测得的C2n符合得很好。仪器将在2013/2014年度中国第30次南极科学考察泰山站建站期间首次对泰山站的C2n进行测量、越冬期间首次对中山站的C2n进行测量,并计划在2014/2015年度第31次南极科学考察期间对昆仑站的近地面大气湍流强度进行测量。
A mobile polar atmospheric parameter measurement system has been developed for measurement of Cn^2, carry- ing out atmospheric optical turbulence measurements by micro-thermal sensors and a three dimensional sonic ane- mometer, respectively. This system has been tested for about 500 hours in Hefei and Shanghai, with Cn^2 measure- ments using independent methods agreeing well. The instrument will be used to determine Cn^2 at Taishan Station during summer and Zhongshan Station during winter for the first time during the 30th Chinese National Antarctic Research Expedition （CHINARE） through the 2013/2014 season. We envisage boundary layer turbulence intensity measurements at Kunlun Station will be performed using this instrument for the 31st CHINARE during the 2014/ 2015 season.
