Haseneder-Lind, J.H. Schween Principle The Large Aperture Scintillometer (LAS) is an instrument designed for measuring the path-averaged structure parameter of the refractive index of air (Cn^2) over horizontal path lengths from 250m to 4,5km. Structure parameter measurements obtained with the LAS and standart meteorological observations (air temperature, wind speed and air pressure) can be used to derive the surface sensible heat flux (H).
