摘 要: 干分量的精确确定是利用GPS反演高精度大气可降水量的前提条件,而常用的经验模型在局部地区无法满足要求。为获得高精度的大气可降水量,利用日本地区代号为47646探空站2005年至2010年的探空资料所计算的干延迟作为真值,回归了Tateno地区的对流层干分量延迟模型,通过与3种经验模型的比较,发现所建立的模型比经验模型更合适Tateno地区。当用研究的模型预测2011年1月至8月Tateno地区的干延迟量后发现此模型比经验模型要好。
关 键 词: 大地测量技术其他学科;大气干分量延迟;探空资料;模型改正

Abstract: Determination of dry zenith plays an important role on the retrieval of precipitable water content using GPS, but the commom empirical models can’t meet the requirements in part areas. In order to obtain the precise atmospheric precipitable water, this paper took the model of tropospheric dry delay based on the radiosonde data of Japanese 47646 station during 2005-2010 as real value, and recurred the model of tropospheric dry delay in Tateno region. Through comparison with three empirical models, it was found that the model proposed in this paper was more suitable than empirical modes in Tateno. In addition, it was proved that this model was better that the empirical modes when forecasting the dry delay content based on the data of January to August in 2011 in Tateno region.
Key words: other subjects of geodetic surveying technique; atmospheric dry delay; radiosonde data; model correction
