铂电阻地表温度与玻璃液体地表温度分析对比

Contrastive Analysis of PRT Geothermometer and Liquid Geothermometer

通过2010年不同天气条件下铂电阻地温传感器与玻璃液体地温表对比观测获取数据分析,不同典型天气条件下(无云、降水、低温阴天等),观测差值的变化情况。结果表明:观测结果差值大小,主要受太阳辐射和下垫面状况影响。无云时两者受太阳辐射影响较大,观测值在早上(或夜间)至12时之前较小,12时至16时较大,低温阴天覆盖时两者的观测差值日变化较小,降雨时下垫面状况发生变化,不受太阳辐射影响,两者的观测差值会逐渐减小。

Based on contrastive analysis of the observe data from PRT geothermometer and liquid geothermometer under different weather condition in 2010, the change of adjustment of observe data in different weather condition such as cloudless, precipitation, low temperature cloudy sky. The results showed that the solar radiation and the condition of underlying surface were the primary factors of observe adjustment. The observe adjustment was lesser in the morning to before 12： 00, larger between from 12：00 to 16： 00; the daily changes of observe adjustment was lesser in low temperature cloudy sky day, the adjustment will diminishingly when there is no sun radiation effects and the condition of underlying surface will be changed in rainy day.
