2.
ICAO Station Identifier:
KPIT
This is the location for which the METAR pertains.

22015G25KT
220
is the 3 digit true direction to the nearest 10°. Airport advisory
service, ATIS and ATC towers report wind direction as magnetic.
“VRB” in this place indicates variable winds less than or equal to 6
knots. If wind direction is varying more than 60° with speeds over 6
knots, an entry similar to “180V260” will be displayed in this place.
This example actually shows wind direction varying by 80°.
15
is the 2 or 3 digit wind speed (in knots).
25
is the 2 or 3 digit wind gust speed in knots (
KT
) because it follows a
G
(Gust).
6.
Visibility:
3/4SM R28R/2600FT
3/4
indicates 3/4 statute mile (
SM
) visibility.
Runway Visual Range (RVR) for
R28R
(runway 28 right) is 2600 feet
(
2600FT
). An “M” in this distance number indicates visibility is less
than the lowest reportable sensor value. A “P” indicates visibility is
greater than the highest reportable sensor value.
