In a METAR, civil aerodromes may include wind shear if reported along the take off or approach paths in the lowest 1600 ft with reference to the runway.
#Airport weather indicator code
Significant recent weather observed in the period since the last routine observation will be reported by using the code letters for weather preceded by the letters RE e.g. QNH is stated to the nearest whole hectopascal (equivalent to a millibar) rounded down and preceded by the letter Q e.g. No significant weather at or in the vicinity of the aerodrome.Īir temperature and dewpoint are reported in whole degrees Celsius, e.g.No CB or TCU and no cloud below 5000 feet or Minimum Sector Altitude (MSA) (whichever is the greater).The Visibility, Cloud, and Weather groups are replaced by the term CAVOK (cloud and visibility OK) when the following conditions exist simultaneously: When there are no clouds of operational significance to report, no CB or TCU and CAVOK is not appropriate, the abbreviation NSC (No Significant Cloud) is used. When the vertical visibility has not been measured, the group will be VV///. Sky obscured is given as VV followed by the vertical visibility in hundreds of feet. Significant convective cloud ( CB or TCU) if not already reported.Selection of cloud layers reported is made as follows:

Note that in area and route forecasts, heights are AMSL or standard pressure altitudes. Weather is indicated by up to 3 groups comprising symbols and letters from the following: - = slightĮ.g - FZDZ = Slight Freezing Drizzle + SHRASN = Heavy Shower of Rain and Snow REUP = Recent Unidentified Precipitation.Ĭloud amount is reported as FEW = few (1-2 oktas), SCT = scattered (3-4 oktas), BKN = broken (5-7 oktas) or OVC = overcast (8 oktas), followed by the height of the cloud base in hundreds of feet above aerodrome elevation e.g.
