| 摘 要： | 选取陕西省5个基准站2003年1月至2007年12月自动站和人工站平行观测气温和相对湿度资料,研究同一地点温湿传感器校准(更换)后人工站和自动站月对比差值的变化。研究表明,温湿传感器校准(更换)后易形成两个不同的人工与自动站对比差值序列,对比差值突变的节点是今后进行单站资料订正非常关健的依据。

| Abstract: | Based on the parallel observation data of manual and automatic observations from 5 basic stations from 2003 to 2007, the influence of calibration/replacement of temperature and humidity sensors on the differences between automatic-manual observations is studied. The results indicate： there were two different differences after calibrating or replacing temperature and humidity sensors. It is essential for single-station data correction to find the abrupt change points of these differences. |
