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:
