| 摘 要： | 利用广东省能见度自动观测系统22个站点2011年的人工观测和自动观测的能见度资料,分析了人工观测与自动观测的能见度资料的相关系数、均方根误差等,并对自动观测资料进行了订正。分析结果显示:人工观测与自动观测能见度的分布大致相同,表现为沿海的能见度高于内陆,粤东高于粤西,主要低能见度区域集中在珠江三角洲和粤西的内陆地区;自动观测能见度的准确性主要受到仪器工作原理局限性、气溶胶类型和气象条件的影响。对能见度自动观测资料订正结果显示:订正后,在低能见度时,大部分站点的均方根误差在3km以内;在高能见度时,大部分站点均方根误差在8km以内,平均为6km左右。利用统计方法对器测能见度值作数据订正,能有效减小测量误差,使能见度自动观测系统能基本满足能见度自动化观测需要,特别是低能见度事件的服务需求。

| Abstract: | The measurements of visibility sensors from 22 stations of the Guangdong Automatic Observing System of Visibility are analyzed by compared with the manual observation data of visibility. The results show that the visibility from two approaches had a similar distribution in Guangdong: visibility in coastal areas is higher than that in inland areas; visibility in the east is higher than that in the west; and the Pearl River Delta and the eastern inland have the lowest visibility in Guangdong. The reasons affecting the accuracy of automatic visibility observation include the limitation of visibility sensors, the types of aerosols, and meteorological conditions. After correcting, RMS is smaller than 3 km when the visibility is low, and smaller than 8 km (the mean value is about 6 km) when the visibility is high. Using the statistic method to correct the measurements of the visibility sensor helps reduce metrical errors effectively. After correcting, the Visibility Automatic Observing System in Guangdong can satisfy the needs of automatic observation, especially for low visibility events. |
