Which type of weather data does RAWS measure?

The correct answer highlights the core functionalities of the Remote Automated Weather Stations (RAWS), which are specifically designed to monitor and collect critical weather data essential for various applications, particularly in fire management and natural resource monitoring.

RAWS typically measure temperature, humidity, precipitation, wind speed, and wind direction. Each of these elements plays a significant role in understanding weather patterns and conditions. For instance, temperature and humidity are vital for assessing the likelihood of fire ignition and spread, while precipitation informs about moisture levels in the environment. Wind speed and direction are crucial for predicting fire behavior, as they significantly affect how fires spread.

The other options include measurements that, while relevant in meteorology, do not reflect the primary focus of RAWS. Atmospheric pressure is important but not included in the main measurements of RAWS. Wind chill, solar radiation, and dew point, as well as cloud cover, air quality, and visibility, encompass a broader range of meteorological data that falls outside the specific parameters that RAWS is designed to monitor regularly. Thus, B reflects the most accurate representation of what RAWS specifically measures.
