Turbulence around a solar telescope as deduced from angle of arrival statistics. A comparison with microthermal measurements.
Abstract
Summary. Optically deduced nearby turbulence profiles are compared with thermal profiles secured with radiosondes. Good agreement is observed as far as the distribution of turbulent energy is concerned up to two hundred meters along the line of sight. The differences observed between the optical and thermal value of the turbulence total energy, may be interpreted assuming that optical and "in situ" soundings partially detect the same turbulence in the lowest layers, but that a strong turbulence is present at heights above two hundred meters, reached only by the optical method.
