Note 1: Javascript must be enabled.

Note 2: US-specific METAR format is not supported.

Note 3: When copy-paste: in some cases add one space behind the METAR, otherwise the last part called "TREND" will not, or only partly, decoded.

Note 4: METARS of military airfields contain behind the QNH a colour state. The first colour mean the actual condition, if a second colour is given this means an outlook for the next 2 hours. The colour state decoding:  

  Visibility / lowest cloudbase (3 oktas or more) >= 2500 ft 1500-2499 ft 700-1499 ft 300-699 ft 200-299 ft < 200 ft
>= 8 km   BLU WHT GRN YLO AMB RED
5000-7999 m WHT WHT GRN YLO AMB RED
3700-4999 m GRN GRN GRN YLO AMB RED
1600-3699 m YLO YLO YLO YLO AMB RED
800-1599 m AMB AMB AMB AMB AMB RED
< 800 m RED RED RED RED RED RED

 

Note 5: Although the decoder has been tested it still might contain some erros. If you find some of them please contact me.
