中文摘要:利用四川5个能见度自动观测站2012年整年数据与人工平行观测数据进行对比分析。结果表明，当能见度小于3km时，能见度自动观测与人工观测差异较小，在此能见度范围下人工观测结果小于自动观测结果，能见度自动观测结果可以代替人工观测结果。当能见度为3-10km时，由于观测员自身的视力、习惯以及对“能见”的最远目标物和“不能见”的最近目标物的不明确，导致能见度自动观测和人工观测结果差异偏大至-1.62km，自动观测结果开始小于人工观测结果。当能见度大于10km时，差异加剧。

Comparative Analysis Visibility Automatic and Artificial Observation Data

Abstract:Used the data of year 2012 from five visibility automatic stations Compared and analyzed.The results showed that when the visibility less than 3km,visibility automatic observation and artificial observation had little differences. In this range of visibility, artificial observation results were less than the automatic observation results, and visibility automatic observation results can replace artificial observations.When visibility was 3-10km,due to the observer’s vision, habits, and the farthest and the latest target is not clear, visibility automatic observation and artificial observation results were partial to -1.62km, and automatic observation results begun to less than artificial observations.When the visibility was more than 10km, the intensifying was differences.
