摘　　要：讨论在自动气象站现场校准中一些需要改进的校准方法和超差传感器的调整方法。在将近2年对74个自动气象站的温湿度传感器、风向风速传感器、气压传感器、雨量和蒸发传感器的现场校准中,不断改进校准方法,对超差传感器进行调整。结果表明:气温传感器和风向传感器的校准方法需要改进,湿度传感器、气压传感器、雨量和蒸发传感器超差时可进行适当调整,使传感器误差值达到最小。Some calibration methods needing improving and adjustment methods of overproof sensors in the AWS are discussed. The various overproof sensors were adjusted while the calibration methods have been improved in the recent 2 years in 74 calibration cases of various sensors, such as temperature and humidity, wind direction and velocity, pressure, rainfall, and evalmration sensors. The result shows that it is necessary to improve the temperature, wind direction and velocity sensors and reduce the overproof errors by adjusting various sensors.
