How is "light snow" abbreviated in a METAR?

In METAR reports, "light snow" is abbreviated as "SN." This abbreviation is part of the standard meteorological terminology used internationally to ensure clarity and uniformity in reporting weather conditions. In METARs, "SN" signifies snow precipitation, and when combined with descriptors such as "light," it provides pilots and meteorologists with essential information about current weather conditions impacting flight operations.

The use of "SN" for snow is widely recognized in aviation meteorology. This abbreviation is further detailed in the Aeronautical Information Manual (AIM) and other aviation weather sources to maintain consistency and prevent misunderstandings across different regions and situations. Understanding this standard is crucial for interpreting weather reports accurately, especially in aviation where precise weather data is vital for safety.
