The Aircrew Quick Reference Guide to the METAR and TAF Codes helps aircrews quickly and clearly translate METAR and TAF codes into plain language. See Attachment 1 for a list of source documents. METAR reports are observed weather conditions while the TAF indicates forecast conditions. Both are lines of text made up of coded data groups
Some stations make regular reports more frequently, such as Pierce County Airport (ICAO code: KPLU) which issues reports three times per hour. Some METARs are encoded by automated airport weather stations located at airports, military bases, and other sites.
