In a METAR report, what section immediately precedes the remarks section?

In a METAR report, the Altimeter section is crucial as it provides pilots and meteorologists with current atmospheric pressure information expressed in inches of mercury (inHg) or hectopascals (hPa). This measurement is essential for calibrating altimeters, which are necessary for maintaining appropriate flight altitudes and ensuring safety in aviation operations.

The remarks section follows the Altimeter reading, often providing additional information that may not be included in the standard parts of the METAR report. This includes anything from significant weather events to notes on runway conditions. By recognizing that the Altimeter section directly precedes the remarks, it's clear that vital information about atmospheric pressure is set before any supplementary notes that could further inform users of the weather reporting.

Understanding the structure of a METAR report, including what comes before the remarks section, helps in effectively interpreting the data provided for flight planning and safety.
