What is the final element of the body of the METAR report?

The final element of the body of the METAR report is the altimeter setting. In a METAR report, the sequence of information presented is standardized to ensure clarity and uniformity. The report begins with data about the location and time of the observation, followed by wind information, visibility, weather phenomena, sky condition, temperature, and dew point. After all these parameters are reported, the altimeter setting is provided.

The altimeter setting is expressed in inches of mercury or hectopascals and is critical for pilots to ensure their altimeters are calibrated correctly for safe flight operations. This allows for precise altitude measurements, which are vital for maintaining safe separation between aircraft, especially during takeoff and landing phases.

Although temperature, dew point, and visibility are important elements of the METAR report, they are reported earlier in the sequence, making the altimeter setting the last piece of information that completes the current observation. Therefore, recognizing the altimeter setting as the final element reinforces an understanding of the structure and significance of the METAR report format.
