Question On UK Metars

Wed Oct 29, 2008 10:18 pm

What do the terms NDV and NCD denote in a metar. Several times now I have seen a metar that reads for visibility 9999 NDV and for ceiling just NCD. Thanks in advance. Several of us have googled and found nothing.

Not sure how you use Google??

A simple "METAR NDV" or "METAR NCD" returns many explanations!

"What is the meaning of the NDV and NCD groups in METAR/SPECI?
These groups only appear in METAR AUTO, i.e. fully automated messages. The NDV group is appended to the visibility meter value to indicate that, as we have only one visibility meter per site, there is No Directional Variation reporting capabilty (as there is with manual reports). The NCD group reports that there has been Nil Cloud Detected by the cloud sensor. "
