Body of Report: PARAMETER |
DESCRIPTION |
|
Type of Report (METAR/SPECI) |
METAR is the routine (scheduled) report. SPECI is the
non-routine (unscheduled) weather report. |
|
Station Identifier (CCCC) |
ICAO station identifier. Consists of four alphabetic
characters, e.g., KABC. |
|
Date/Time (YYGGggZ) |
Day of the month, followed by the actual time of the report
or when the criteria for a SPECI is met or noted. Group ends
with Z to indicate use of UTC. For example, 251456Z. |
|
Report Modifier (AUTO or COR)) |
AUTO indicates a fully automated report. No human
intervention. COR indicates a correction to a previously
disseminated report. |
|
Wind (dddff(f)Gfmfm(fm)KT) (dndndnVdxdxdx) |
True wind direction in tens of degrees using three digits.
Speed is reported in whole knots (two or three digits). Gusts
(G) are appended to the speed if required. Group ends with KT to
indicate knots. For example, 23018G26KT. If wind direction
varies by 60°
or more and speed is > 6 knots a variable wind group is also
reported, e.g., 180V250. Direction may be reported VRB
(variable) if speed is £
6 knots, e.g., VRB05KT. Calm winds are reported 00000KT. |
|
Visibility (VVVVVSM) |
Surface visibility reported in statute miles. A space divides
whole miles and fractions. Group ends with SM to indicate
statute miles. For example, 1 1/2SM. Auto only: M prefixed to
value < 1/4 mile, e.g., M1/4SM. |
|
Runway Visual Range (RDRDR/VRVRVRVRFT
or RDRDR/VnVnVnVnVVxVxVxVxFT)
|
10-Minute RVR value: Reported in hundreds of feet if
visibility is £
one statute mile or RVR is £
6000 feet. Group ends with FT to indicate feet. For example,
R06L/2000FT. The RVR value is prefixed with either M or P to
indicate the value is lower or higher than the RVR reportable
values, e.g., R06L/P6000FT. If the RVR is variable during the
10-minute evaluation period, the variability is reported, e.g.,
R06L/2000V4000FT. |
|
Present Weather (w'w') |
Present weather (other than obscurations) occurring at the
station are reported in the body of the METAR/SPECI.
Obscurations are reported if visibility < 7 miles. VA may be
reported with any visibility. BCFG and PRFG may also be reported
if visibility ³
7SM. Some present weather and qualifiers may be reported if
In-the-Vicinity (not at point-of-observation), e.g., TS, FG, SH,
PO, BLDU, BLSA, BLSN, SS and DS. Weather is reported in order of
decreasing dominance. Maximum of three groups reported
(precipitation included in one group; separate groups for other
weather). Automated stations can only report RA, SN, UP, FG, BR,
FZFG, HZ, and SQ without augmentation. See table on reverse for
more information on qualifiers and weather phenomena. |
|
Sky Condition (NsNsNshshshs
or VVhshshs or SKC/CLR) |
Automated stations truncate to three layers up to 12000 feet;
if no layers are detected CLR is reported. At manual stations up
to six layers can be reported; if no layers observed SKC is
reported. Each layer contains the amount (FEW, SCT, BKN, OVC)
immediately followed by the height using three digits, e.g.,
FEW015 BKN030. Any layer containing CB or TCU (manual only) the
contraction is appended to the layer height, e.g., FEW015TCU.
All layers are considered opaque. Vertical visibility (VV) is
reported in hundreds of feet for an indefinite ceiling, e.g.,
VV002. Surface obscuration (manual only) reported using amount
(FEW, SCT, BKN), followed by "000," e.g., SCT000;
remark required. |
|
Temperature/Dew Point (T'T'/T'dT'd) |
Temperature and dew point are reported to the nearest whole
degree Celsius using two digits, e.g., 17/13. Sub-zero values
are prefixed with an M, e.g., 03/M02. |
|
Altimeter (APHPHPHPH) |
Altimeter is prefixed with an A indicating altimeter in
inches of mercury. Reported using four digits; tens, units,
tenths, and hundredths of inches of mercury, e.g., A2990. |
|
Remarks (RMK) -- Divided into two categories: 1. Automated,
Manual (Augmented), Plain Language (Manual Only), 2. Additive
and Automated Maintenance Data. The following describes the
order in which remarks are reported. |

reported in a METAR when the SLP is not available. Precipitation
groups can be reported as missing. |

Footnotes for Weather Phenomena Matrix
1 - Only 1 descriptor shall be included for each weather
phenomena group, e.g., BCFG. Only 2 exceptions exist to
this rule:
VCSH and VCTS.
2 - Vicinity is defined as >0SM (not at point of observation)
to 10SM of the point of observation for precipitation.
Other than
precipitation (VCFG, VCBLSN, VCBLSA, VCBLDU, VCPO, VCSS, VCDS),
vicinity is 5SM to 10SM.
3 - Raised by wind to less than 6 feet above the ground.
4 - TS may be reported by itself if no precipitation is
associated with the thunderstorm.
5 - No intensity is ever given to hail (GR/GS[snow pellets]) or
ice crystals (IC).
6 - Largest hailstone observed has a diameter of 1/4 inch or
more.
7 - Hailstone diameter is less than 1/4 inch. No remark is
entered for hailstone size.
8 - VCTS shall only be used by automated stations. Not a manual
entry. If thunder is heard, TS shall be reported.
9 - Showers (SH), when associated with the indicator VC, the type
and intensity of the showery precipitation shall not
be specified,
i.e., +VCSHRA is not allowed; only VCSH would be reported. VCSH
shall be used to report any type
of precipitation not at point of
observation, but >0 to 10SM.
10 - BR (mist) shall only be used when the visibility is at least
5/8SM, but not more than 6SM.
11 - For FG (fog) to be reported without the qualifiers VC12,
MI13, PR14, or BC15 the visibility
shall be less than
5/8 SM.
12 - VC is used to report any type of fog observed in the
vicinity (5-10SM) of the station.
13 - MIFG (shallow fog) to be reported, the visibility at 6 feet
above ground level shall be 5/8SM or more and the
apparent
visibility in the fog layer shall be less than 5/8SM.
14 - PRFG (partial fog) indicates that a substantial part of the
station is covered by fog while the remainder is clear of
fog.
15 - BCFG (patches fog) indicates that patches of fog randomly
cover the station.
16 - FZFG is any fog consisting predominately of water droplets
at temperatures below 0°C and
visibility less than 5/8
statute miles, whether it is depositing
rime or not.
17 - Volcanic Ash is always reported in the body of the METAR/SPECI
when present. Visibility is not a factor.
18 - SN BLSN indicates snow falling from clouds with blowing snow
occurring. If the observer cannot determine
whether or not snow is
also falling from clouds, then only BLSN shall be reported.
19 - SQ (squall) is a sudden increase in wind speed of at least
16 knots, the speed rising to 22 knots or more and
lasting for at
least one minute.
20 - Tornadoes and Waterspouts shall be reported using the
indicator "+", i.e., +FC.
21 - SS (sandstorm) reported if the visibility is ³
5/16SM and £ 5/8SM. Report +SS
if the visibility is < 5/16SM.
22 - DS (duststorm) reported if the visibility is ³
5/16SM and £ 5/8SM. Report +DS
if the visibility is < 5/16SM.
No more than three weather groups shall be used to report
weather phenomena at or near the station. If more than one
significant weather phenomena is observed, separate weather
phenomena groups shall be included in the report. If more than
one form of precipitation is observed, the appropriate
abbreviations shall be combined in a single group with the
dominant type of precipitation being reported first. In such a
single group, the intensity shall refer to the first type of
precipitation reported, e.g., -RASN FG HZ.
