Template for METAR

Key

M

=

inclusion mandatory;

C

=

inclusion conditional, dependent on meteorological conditions or method of observation;

O

=

inclusion optional.

Note 1: The ranges and resolutions for the numerical elements included in METAR are provided in a separate table following this template.

Note 2: The explanations for the abbreviations can be found in ICAO Document 8400 ‘Procedures for Air Navigation Services – Abbreviations and Codes (PANS-ABC)’.

a To be included if visibility or runway visual range is < 1 500 m; for up to a maximum of four runways.
b ‘Heavy’ used to indicate ‘tornado’ or ‘waterspout’; ‘moderate’ (no qualifier) to indicate ‘funnel cloud not reaching the ground’
