Kipp & Zonen Scintillometer
Help
A scintillometer is a combination of an optical transmitter and a receiver placed at opposite ends of a path above the area that needs to be monitored. Turbulence in the air is caused by variations in temperature, humidity and pressure, and the scintillometer measures these variations using a pulsed beam of infrared light emitted by the transmitter and detected by the receiver. Scintillometers measure the change in refractive index of the air (Cn2). When you plug in the accessory meteorological sensor kit into the X-LAS MkII receiver and enter the characteristics of the measurement site, the scintillometer calculates the sensible heat flux in real time. One of the uses is the calculation of evapotranspiration, a key component in water management. The LAS-Mk2 measures up to distances of 4.5 km and the X-LAS up to 12km (a standard satelite resolution).
