摘　　要：文章分析了目前国家级地面气象观测站中自动气象站地温传感器在现场更换、维修及实验室检定时遇到的问题,提出了适宜的改进方法,并通过实验对改进方法的可行性进行了验证。通过分析实验数据,发现改进后的地温传感器的差值变化范围在±0.02℃内,且对传感器的连续采集能力无影响。The problems encountered in field replacement,maintenance and laboratory verification of ground temperature sensors of automatic weather station in national ground observation stations are analyzed,and appropriate reconstruction methods are proposed.And the feasibility of the reconstruction methods is verified through experiments.By means of analyzing the experimental data,it was found that the variation range of the ground temperature sensor after the modification was within±0.02℃,which had no effect on the continuous acquisition capability of the sensor.
