In automated METAR and SPECI, visibility should be reported in accordance with provisions relevant to METAR and SPECI included in Section 4.2. However, when visibility sensors are sited in such a manner that no directional variations can be given, visibility value reported should be followed by the abbreviation NDV. | |
