What component of RAWS is primarily responsible for measuring atmospheric pressure?

The BARO sensor is specifically designed to measure atmospheric pressure, making it the fundamental component in RAWS (Remote Automated Weather Stations) for this purpose. BARO sensors provide critical data that influences weather predictions and atmospheric studies. By accurately measuring pressure changes, the BARO sensor helps meteorologists understand weather trends and dynamics.

In contrast, an anemometer measures wind speed and direction, which is essential for understanding airflow but does not provide atmospheric pressure information. A thermometer is used for measuring temperature, while a hydrometer is designed to measure the specific gravity of liquids, often related to humidity in this context but not atmospheric pressure. Thus, the BARO sensor is uniquely suited for pressure measurements, providing crucial data for meteorological analysis.
