Parameter to be measured:
Net Radiation (spectral range 0.2-100µm): The net radiation is the energy balance between incoming short-wave and long-wave infrared (IR) radiation relative to surface reflected short-wave and outgoing long-wave IR radiation.
Method:
The NR-Lite sensor is a thermopile sensor. It has on both sides an black absorber and the sensors outputs a voltage. The vaoltage is proportional to the radiation
Equipment:
- NR-Lite sensor
- Mounting gear
- Logger
Advantages:
- Cheap compared to other net radiometers like the CNR 1 from Kipp & Zonen
- resistant
- measures the short and longwave radiation in one sensor
Disadvantages:
- not as precise as CNR 1 or comparable other sensors
- sensitive to wind speed
What to watch out for:
- keep the sensor clean
Problems/Questions:
Links
Projects that used the above equipment: HYGRA – The effect of water storage variations on in-situ gravity measurements and their use for hydrology
Manufacturer: Kipp & Zonen
Dealer: Campbell Scientific Thies Clima

The following paper compares the NR Lite with supposedly more precise instrumentation. Interesting conclusions. Douglas R. Cobos, John M. Baker (2003) Evaluation and Modification of a Domeless Net Radiometer, Agron. J. 95:177–183 (http://agron.scijournals.org/cgi/reprint/95/1/177.pdf)
