  针对广东地区的能见度观测展开分析和研究,提出了适用于能见度观测布局适应性分布研究的新方案,旨在为器测替代目测的能见度监测网建设提供参考。研究表明:利用广东地区86个地面气象观测台站的2009-2011年能见度和相对湿度日均值资料,计算得到了品质因数(Figure of Merit,FOM指数)和空间影响范围因数(Sphere of Influence,SOI指数)对现有的能见度站点进行排名和分类。再根据确定的标准遴选所需的站点,用于筛选的标准为:如果排名低的站点影响的范围内超过50%的区域被排名高的站点影响范围所覆盖,则剔除掉此排名低的站点。最后筛选得出广东地区能见度仪观测站网需要的最少的站点数为43个。考虑到本地的地形以及增加背景站等因素,最后综合考虑广东地区能见度仪观测站网所需要的站点数为51个。
