::summary Instrument for measuring the net radiation on Earth's surface ::
A net radiometer is a type of actinometer used to measure net radiation (NR) at the Earth's surface for meteorological applications. The name net radiometer reflects the fact that it measures the difference between downward/incoming and upward/outgoing radiation from Earth. It is most commonly used in the field of ecophysiology.

Dimensions: diameter of the pyranometer dome is 20 mm."] ::
