摘　　要：利用通辽国家基本站2011年逐日20时气温、湿度、气压资料,分析了自动观测与同期人工观测数据的差异及产生差值的可能原因。分析认为:仪器的测量原理、感应原件的不同、仪器本身的系统误差、观测的时空差异和人为主观因素以及环境因素、采样和算法的不同是造成自动观测与人工观测数据产生差值的主要原因。Using the daily data of temperature, humidity and air pressure at 20：00 from Tong Liao＇s national prin- cipal station in 2011, the data differences between automatic observation and manual observation and the possible causese were analyzed. The analyses showed that the differences of instrument measurement principle and sensing elements, instrument system errors, space-time differences in observation, artificial subjective factors and envi- ronmental factors, different sampling and different algorithms were the main reasons of data difference between automatic observation and manual observation.
