摘要
选取2008年6月的微波辐射计观测数据和同期探空数据进行对比分析。结果发现两者温湿度的相关系数分别为0.994和0.697,都通过了置信度为0.001的显著性水平检验,表明其总体趋势是相近似的。对于廓线的分析采用的是各层的平均值,微波辐射计和探空的结果都反映了温度随着高度呈现递减趋势,而且经过方差分析两者在0.05水平差异不显著。但相对湿度的廓线结果经过方差分析在0.01水平差异极显著。
This paper compared and analyzed the Microwave Radiometer （MWR） observations and the sounding data in June of 2008. It is found that, the correlation coefficient of their temperature and humidity are respectively 0.994 and 0.697, both of which successfully passed the significance level test with credible degree of 0.001, which indicates the similarity of their general tendency. Analyzed on the mean profile of each layer, we found that a reducing tendency of temperature with height was presented from the MWR obervations and the sounding data. Seen from squared bias analysis, their horizontal bias is not remarkable at 0.05, while that of relative humidity at 0.01 is quite significant.
