Scintillometer

From Wikipedia, the free encyclopedia

A Large Aperture Scintillometer (transmitter) for measurement of the sensible heat flux over long distances at Wageningen University measurement site

A Scintillometer is a scientific device used to measure small atmospheric optical disturbances called scintillations, which are caused by fluctuations of the refractive index of air along a propagation path, caused by variations in temperature, humidity, and pressure. Scintillation is usually measured in terms of Cn^2. The device also allows measurements of the transfer of heat between the Earth's surface and the air above it called the "sensible heat flux"[1].

The term Scintillometer has been used, in its original sense (though relatively infrequently today except in a few specialized instances (such as the mining industry for checking drillcores for the presence of uranium)) to refer to a Scintillation counter, which measures ionizing radiation.
