What information does the term "remarks" provide in a METAR?

The term "remarks" in a METAR provides additional weather observations that complement the primary weather data reported in the METAR. This section can include a variety of pertinent details such as significant weather changes, specific conditions like runway conditions, and information about any phenomena such as fog or hail. The remarks section serves as a crucial tool for pilots and meteorologists to gain insights beyond the standard weather measurements, allowing for better situational awareness and flight planning.

While options like wind speed details, temperature data, and flight path information are important aspects of a METAR, they are typically included in the main body of the report rather than in the "remarks" section. Therefore, this distinction reinforces why "additional weather observations" is the correct understanding of what "remarks" provides in a METAR.
