Table 1-15 -- Typical METAR or SPECI observation
Type of Report
Aviation weather observations are classified as either a METAR or a SPECI taken
between 45 59 minutes past the hour. A METAR is a routine scheduled report used
for reporting surface meteorological data.
A SPECI contains all the data elements found in a METAR, but it is an unscheduled
report. A SPECI is taken when a significant change in weather occurs between the top
of the hour to 44 minutes past the hour or an aircraft mishap has occurred.
