大气能见度大气能见度atmosphericvisibility视力正常的人能从背景（天空或地面）中识别出具有一定大小的目标物的最大距离。又称气象视程。按观测者与目标物所在高度和相对位置，大气能见度可分为水平能见度、斜视能见度和垂直能见度。气象观测中的能见度一般指水平能见度，即水平方向上的有效能见度。所谓有效能见度是指四周视野中一半以上范围都能看到的最大水平距离。航空部门也常用斜视能见度和垂直能见度。能见度的好坏取决于观测者与目标物之间的大气透明度（它随大气及其所含杂质对光的散射和吸收的强弱而变化）、目标物和它所投影的背景面上的视亮度对比以及观测者的视觉感应能力。能见度目标物要分布在各个方向、不同距离上。白天应尽可能选以天空等为背景的大小适度的目标物。把勉强可见的目标物的距离（可利用地图等测定）作为能见度。夜间，则观测一定强度的灯光的能见距离，折算出相当于白天的能见度。能见度在交通运输、航空、航海、军事活动、大气污染和大气物理研究中应用广泛。
