Abstract:

By using the GAMIT soft,the water vapor content of atmosphere was retrieved based on the ground-based GPS data from January to October 2009 in Tazhong station.The diurnal variation curve of PW were obtained by analyzing averaged data of each month.The results are as follows:the diurnal variation of the whole year’s water vapor content in the hinterland of the Taklimakan Desert was obvious and it presented a sine curve.The maximum appears at 08:00 and 23:00 with the values of 13.63 mm and 13.85 mm.The minimum appears at 01:00 and 14:00,12.91 and 12.28 mm,respectively.Atmospheric water vapor content is the least in January with the average value of 7.09 mm,and the minimum value was 0.95 mm at 13:00 on January 21 in winter of 2009.And it is the most in July with the value of 20.01 mm,the maximum value is 34.75 mm at 07:00 on August 6 in summer of 2009.The maximum diurnal variation range of water vapor content is in October,and there is not significant fluctuations in February.

Key words: Taklimakan Desert, atmospheric water vapor content

摘要:

利用2009年1~10月塔中站地基GPS观测的大气水汽含量数据,分析了其在不同季节的日变化特征。结果表明:塔克拉玛干沙漠腹地全年大气水汽量的日变化特征呈正弦曲线,变化稳定,峰值出现在08时(北京时间,下同)和23时,为13.63 mm和13.85 mm;谷值出现在01时和14时,为12.91 mm和12.28 mm。1月大气水汽含量最少,平均值为7.09 mm,极小值出现在冬季1月21日13时,为0.95 mm;7月水汽含量最大,平均值达到20.01 mm,水汽含量极大值出现在8月6日7时,为4.75 mm,水汽含量日变化幅度最大月份为10月。
