  • Thanks for that info, in fact I’m just preparing for my PPL over on this side of the ocean.

    A02 or A01 is, as far as I know, appended to every METAR that is generated by an ASOS or AWOS machine. That mark will be missing if it was generated by a human, say at a larger airport that has an ATIS system.

    I fly from a bigger airport with its own CTR and ATIS, but the METAR is automated, except it just says AUTO, no A01/02. Wonder if that’s also an EASA/FAA difference.

    You’ll hear AWOS systems say “Visibility. More than. One. Zero.”

    We are pampered then, we get a fluid pleasant female voice announcing “visibility one-zero kilometres or more” on the automated ATIS reports. I’m not sure that AWOS and ASOS exist here though, but we have CTRs and ATIS systems almost touching each other in these parts everywhere anyway.





  • So I actually went and tried to decode this because I was horrified that I didn’t understand half of this. Turns out I don’t usually see freedom units or volcanic ash tornadoes.

    • METAR - That’s just specifying this is a meteorlogical report as opposed to something else like a TAF or a NOTAM
    • KNYC - This should be the airport the report is given for, KNYC doesn’t exist, but if it did, it would be somewhere in the US since it starts with a K
    • 251600Z - means the report is dated for the 25th, 16:00 UTC
    • 18035G45KTS - this is the wind, coming from 180 degrees, 35 knots gusting 45, so a lot of wind
    • 6SM - so this was weird, but it’s just US weirdness, visibility 6 statute miles, so equivalent to the 9999 message everywhere else
    • VCFCFZVA - in the vicinity funnel cloud, freezing, volcanic ash (freezing volcanic tornadoes, yay!)
    • +BLUP - heavy blowing unknown precipitation, so a lot of something coming your way
    • NOSIG - no significant change expected, this is your life now
    • LTG OHD - surprisingly accurate, lightning overhead
    • A3808 - again, weird US shenanigans, altimeter setting 38.08 inches of mercury, which is not really consistent with that major storm but I digress
    • RMK - remarks, this is how meteorogists say “oh, by the way”
    • A02 - I’m an automated weather station who also can differentiate precipitation (pretty high strung for someone who just announced +BLUP)
    • SLP130 - sea level pressure is 1013 hPa, which means that this airport is at around 2100 m above sea level
