I removed airline because all pilots use METARs, not just airline pilots. bDerrly talk contr 14:05, 21 July 2005 (UTC)
-- Ymorby 22:42, 9 January 2006 (UTC) Added runway status information (9949//91) Information retrieved from Meteo France and translated into english
--Perhaps it's best not to mention the RMK section in any detail, because it is basically an undefined section where countries can add whatever they want - the US chooses to use it in the way described. Also, METARs are reported half-hourly from many airports, not hourly - in the UK half-hourly is the norm BaseTurnComplete 02:46, 21 February 2006 (UTC).
-- Famartin 06:14 14 February 2006 (UTC): Removed edits of previous wikipedian in the US/Canada METAR code. First, the comment about temperature is inaccurate: US ASOS systems are designed to be accurate to the nearest degree Fahrenheit, so they DO have that amount of accuracy.
Second, not all of the RMK section is not duplicated in Canada. They do have remarks in Canada, including SLP... here's an example: METAR CYYZ 130800Z 29016KT 15SM FEW026 BKN067 M03/M07 A2977 RMK SC2AC5 SLP090=

-- Graphex 20:14, 27 November 2006 (UTC) Removed erroneous abbreviation (METAR does NOT mean METeorological Aerodrome Report) and added in the original French words from which METAR was derived. Updated definition to FAA standard, "Aviation Routine Weather Report".
under "External links" -> "format specifications", I removed the broken link:
I couldn't find the current location of such a document on WMO.ch. It sounds useful, though, so if it turns up, we should replace the link. -- Amoore 19:08, 29 May 2007 (UTC)
The renaming of this article a few days ago seems really strange. For one thing, there does not seem to be any disambiguation or an article on the other subject proposed that would support the need to disambig. Second, since Wikipedia is case sensitive as far as I know, METAR shouldn't conflict with Metar. But worst is the choice of title. I don't think anyone would guess that would be the right title, nor does it seem to make a lot of sense. If the article can't just exist as METAR, I'd suggest METAR (weather report).
Can someone please move this article back, or a least to a shorter, English language title? -- skew-t 22:19, 12 November 2007 (UTC)
"CambridgeBayWeather" arbitrarily removed a number of links, apparently without discussion. The U.S. NOAA link that he put in for US METARs is a poor substitute. I've added one of the links back. Gladtohelp ( talk) 18:01, 30 December 2007 (UTC)Gladtohelp
Ah, there we are. The dreaded "spam link", a term used with such alacrity. We should be selecting links based on their merit and nothing else. Here are your arguments, one at a time:
(1) "Flightcentral is an advertising service" - if you want to cull every website that sells advertising, you better get busy. You've got many thousands to go. This measure is clearly not used anywhere else in Wiki to determine a link's inclusion.
(2) "has less US airports than the NOAA" - wrong. FlightCentral includes every airport in the United States and even marking those that are private.
(3) "restricted to the US in what is a worldwide article" - Again, there are thousands upon thousands of external links in Wiki that refer to a US site in worldwide articles.
(4) "as a METAR link it's just spam" - put in LAX into NOAA and see what you get. Instead of putting in the K for you, it confuses you with "No METAR observation from LAX is available in our system." NOAA's METAR engine is about as barebones as it gets. FlightCentral color codes the ZULU time, reports Current Zulu Time on the page, and places a color-coded icon in front of the METAR to specify which type of flight rules exist. It clearly is a superior reporting tool for METARs.
I haven't touched your pet NOAA link, but I am reverting your deletion of the FlightCentral link. In the spirit of Wiki, I'd suggest you avoid further deletions until you discuss it. Gladtohelp ( talk) 14:08, 31 December 2007 (UTC)gladtohelp
I think it should be noted that even though AWOS stations can only detect cloud heights up to 12,000ft, METARS can have readings of cloud bases much much higher. There should be a note somewhere in this article about METARS having collected reports from AWOS/ASOS stations + weather balloons + human remarks. If you'd like an example of high altitude cloud reporting check out KMIA (2008/08/12 15:53 UTC):

I've expanded the METAR acronym in the very beginning of the article, but it was reverted back:

BTW, Wikipedia's definition of vandalism:

Can someone show me "a deliberate attempt to compromise the integrity of Wikipedia"?

the second part of the introduction (standardization) is not standard grammatical english [sic] — Preceding unsigned comment added by 68.236.121.54 ( talk) 19:26, 2 February 2012 (UTC)
310V290 is not a good example for the variation in wind direction, even though it is a real world example. According to the Manual WMO-No. 306 (2011), Volume I.1, chapter 15.5.3, this group should be included only if "the total variation in wind direction is 60° or more but less than 180°" and that "the observed two extreme directions ... shall be given ... in clockwise order". 310V290 would therefore be decoded as a variation of 340°. Actually, VRB03KT should have reported instead (chapter 15.5.2). Any ideas whether it would be best to adapt just this group, use a different real world METAR, or add a comment?
Please also correct the description for code for the runway in the group 9949//91. Chapter 15.13.6.1 says: "Code figure 88 indicates "all runways"; code figure 99 shall be used if a new runway state report is not available ... in which case the previous runway state report will be repeated". The runway state was reported last at 19:30 UTC the previous day (0449//91) and was repeated in every METAR until the runway was reported cleared (04CLRD//) at 16:30 UTC.

The WMO code table's description should indicate in what sequence the 'nnn' codes are specified (low, middle, high could be inferred by the table, but being specific would be good) — Preceding unsigned comment added by Sejtam ( talk • contribs) 09:00, 13 March 2013 (UTC)

VMC and IMC both link to this page (both are described as Aviation flight categories) but are not listed on it, which is confusing. — Preceding unsigned comment added by 163.1.246.64 ( talk) 14:43, 11 February 2020 (UTC)
There are many sources of live METAR reports. Could some clever Wikipedian add the code to this page that would link to one of those sources and show the current METAR for a couple of well-known airports such as London Heathrow, Hong Kong, Los Angeles, etc? I think that would make the page interesting. — Preceding unsigned comment added by 129.210.115.100 ( talk) 21:20, 20 February 2020 (UTC)
Unless I have missed it, although the individual components of a report are explained, there is no description of the overall structure of a report. Is the order of the components fixed? If the order is not fixed, how are they identified? (The components do not, for example, seem to begin with an identifier.) Are all components obligatory? Bill ( talk) 23:53, 3 October 2021 (UTC)
