What does this indicate on a METAR?

Don't quite know which section to post this, but here goes

Have never seen this before... what does 29519095

what does 112///93 indicate?

YLO YLO is the military code for cloud base and visibility... the fact that these digits appear before the RMK makes me think it's not military related. Any idea...

Looks more like runway state codes due to the snow. Does this airfield have runways 11 and 29 perhaps?

[Glamdring]

Aye, it's a snowtam.

Decodes as...

RW 29
Wet Snow
10% or less of runway covered
90mm depth
Braking Action good

RW 11
Wet/Water patches
Braking action medium

Unable to stop myself being a pedant, it's actually a MOTNE group.

Here's a good decode (http://www.hilmerby.com/fom/proc_motne.html).

If you have an ipod etc there is a very good App called Snowtamlite which decodes the figures for you. (assumming you are allowed to use multi media devices in your ops room :{ )

Spitoon I think MOTNE is w.f.u.

SI CAP 493 Mats pt1 13/12/10 uses the phrase Runway State Reports / Runway State Groups ( formally known as MOTNE ).

Why do they keep changing everything?????

Thanks for the update Ayr

AyrTC,
Well spotted.
Of course way back, ATCOs would probably have had their own copies of MATS Pt.1 and would have all known this, (from the hand-incorporated personal amendment), resulting in a cascade of correct answers.
It took me a while to dig the information out from the CAA website.

MOTNE=Met Office Teleprinter Network.......was phased out with the Stevenson Rocket!!:cool::cool:

[ZOOKER]

fisbang,
Sorry, but you're not quite there.
MOTNE = Meteorological Operational Telecommunications Network Europe. :ok:
P.S. Apologies, but at the risk of being sadly pedantic the locomotive was actually called 'Stephenson's Rocket'.

[hotmetal]

Goodness knows why in the 21st century important information about runway state is given in some sort of code. Madness. Why should I have to 'decode' it?

[Spitoon]

Well I guess it could be done in plain language....but I'd have trouble with the Chinese ones.

[max1]

The decode actually reads

Get out of the Mother Country, migrate to the Antipodes where you can experience floods, cyclones and bushfires. Much, much nicer.

MOTNE=Met Office Teleprinter Network

Actually, Met. Operational Teleprinter Network Europe

Im filling MOTNE during the winter, because its decoded in ATIS. Dont need to read that stuff to every plane, they can listen it on ATIS.
