Based on the general investigation of manually observed historical haze records from 1951 to 2008 in 105 national weather stations in Xinjiang, it is found that the historical manual haze records do not accord with the actual situation. In order to explore the causes of these anomalies, by means of the historical data statistics, questionnaires, inductive analysis method, as well as the views and suggestions from observers, forecasters, and management personnel about haze monitoring, main problems in haze monitoring are summarized, and optimization strategies and measures for the problems are presented, which have been applied in meteorological stations in Xinjiang and achieved good results.
