True or False? METARS are reported in MSL.

METARs are aviation routine weather reports that provide vital information about current weather conditions at an airport or weather station. These reports include various parameters like temperature, dew point, wind speed and direction, visibility, and cloud cover. When discussing altimeter settings, METARs refer to barometric pressure readings adjusted to sea level, but the elements of the report, such as cloud heights, are generally relative to the airfield or the reporting location itself, not strictly reported in mean sea level (MSL).

While certain parts of weather reports, like altimeter readings, are indeed calibrated to MSL to standardize pressure readings across different elevations, the overall report itself encompasses a broader range of data that can be measured relative to the ground level of the observation point. Thus, stating that METARs as a whole are reported in MSL would be misleading because not all components of the METAR adhere strictly to this measure.
