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.
