What is the position of the station identifier in a METAR/SPECI coded report?

In a METAR or SPECI report, the position of the station identifier is second. The report begins with a four-letter identifier that signifies the specific weather station providing the information. Following this identifier, the report includes the type of report—whether it is a METAR or SPECIMETAR, usually indicated with "METAR" being the first element, followed by other data elements such as the date, time, wind information, visibility, and weather phenomena.

This structure is essential for users of the report, such as pilots and meteorologists, to quickly identify the station of origin, which is crucial for understanding the geographical context of the weather data being presented. The placement of the station identifier as the second element facilitates clarity and consistency across various reports, ensuring that consistent reporting practices are maintained in aviation and meteorological communications.
