Does the SI-111 need to be protected from short-wave radiation?

There are two accuracy specifications listed for the SI-111:

  • One for when the difference in the target and sensor body temperatures is less than 20°C (more accurate)
  • One for when the difference in the target and sensor body temperatures is greater than 20°C (less accurate)

Using a radiation shield with the sensor helps keep the sensor body temperature in close approximation to the ambient air temperature. Ultimately, the need to protect the sensor from short-wave radiation is dependent on what is being measured and under what conditions. For example, Campbell Scientific recommends using a radiation shield for canopy measurements.
