METAR and SPECI — examples of elements

Note 1: Consult the ‘Template for METAR and SPECI’ (Appendix 1 to Annex V (Part-MET) to Regulation (EU) 2017/373) to identify the mandatory (M), the conditional (C) or the optional (O) elements.

Note 2: The ranges and resolutions for the numerical elements included in the METAR and SPECI are provided in Appendix 1 to Annex V (Part-MET) to Regulation (EU) 2017/373.

Note 3: The row numbers in the ‘Ref.’ column are included only for clarity and ease of reference, and are not part of the METAR and SPECI. They do not correlate with the ‘Ref.’ column in the ‘Template for METAR and SPECI’ in Appendix 1 to Annex V (Part-MET) to Regulation (EU) 2017/373. Refer to the ‘Element’ column when cross-referencing.
