摘　　要：本文对谷城县国家基本气象观测站检定过程中发现的备份站深层地温套管内积水问题进行了处理,对深层地温温度传感器进行了周期检定,并对检定前后的深层地温数据进行了对比分析。结果表明,备份站深层地温80、320 cm套管积水主要是由于降水引起的,套管内积水会引发深层地温数据异常偏高,其中80 cm深层地温偏高13.21℃,320 cm深层地温偏高13.18℃。在对积水进行处理后,备份站深层地温恢复正常,两站深层地温数据一致性较好。同时,为了确保深层地温传感器的正常运行和观测数据的准确可靠,应按照规定的时间进行周期检定和维护工作,尤其要做好日常维护和降水后检查深层地温进水情况。This article dealt with the problem of water accumulation in the deep ground temperature casing at the backup station of the National Basic Meteorological Observation Station of Gucheng County.The deep ground temperature sensor was periodically checked,and the deep ground temperature data before and after the verification were compared and analyzed.The results showed that the water accumulation in the casing of 80 cm and 320 cm was mainly caused by precipitation.The water accumulation in the casing causing abnormal high ground temperature data in the deep layer,the ground temperature was 13.21℃higher than normal in the 80 cm and 13.18℃higher in the 320 cm.After the treatment of the accumulated water,the deep ground temperature of the backup station returned to normal,the data of the two stations had good consistency.At the same time,in order to ensure the normal operation of the deep ground temperature sensor and the accurate and reliable observation data,periodic verification and maintenance should be carried out according to the prescribed time,especially the daily maintenance and inspection of deep ground temperature water intake after precipitation.
