Which weather station source measures solar radiation?

• A. Thermistor
• B. Pyranometer
• C. Wind Vane
• D. Anemometer

Answer: (B)

The pyranometer is the instrument used to measure solar radiation, making it the correct choice. This device specifically captures the intensity of solar radiation reaching a surface, which is crucial for understanding solar energy input for various applications, including landscape irrigation and water-efficient practices. By quantifying solar exposure, landscape professionals can tailor their irrigation schedules and plant selections to align with the local climate conditions, ultimately promoting efficient water use.

In contrast, a thermistor is utilized for measuring temperature, a wind vane provides information about wind direction, and an anemometer gauges wind speed. While all these instruments play significant roles in weather data collection, they do not measure solar radiation like the pyranometer does. Understanding the specific function of each tool helps in selecting the right instruments for assessing environmental conditions impacting landscape management and water efficiency.
