Characterization of daytime atmospheric turbulence profiles is needed for the design of a
multi-conjugate adaptive optical system. S-DIMM+ (solar differential image motion monitor+) …

In solar observations, the vertical distribution of turbulence can be detected with a
multidirectional Shack–Hartmann wavefront sensor, based on SLODAR or S-DIMM+. By …

We present the results of an 18-month study to characterize the optical turbulence in the
boundary layer and in the free atmosphere above the summit of Mauna Kea in Hawaii. This …

Atmospheric turbulence reduces the image quality and resolution of ground-based optical
telescopes. Future large solar telescopes (eg the CGST, China Giant Solar Telescope) …

A characterization of the optical turbulence vertical distribution (C 2 N profiles) and all the
main integrated astroclimatic parameters derived from the C 2 N and the wind speed profiles …

We present the first complete seasonal variation study extended over 1 year, of all the
principal astroclimatic parameters above the San Pedro Mártir Observatory, simulated with …

We present the results of monitoring the speed of optical turbulent layers in the atmosphere
above San Pedro Mártir, Mexico, during 15 nights in 2000 May. The data were obtained …

As telescopes become larger, into the era of∼ 40 m Extremely Large Telescopes, the high
resolution vertical profile of the optical turbulence strength is critical for the validation …

The characterization of the optical turbulence structure at an astronomical site requires a
proper data base of the refractive-index structure constant,. Our team has been obtaining …

We report the development and first results of an instrument called Low Layer SCIDAR
(Scintillation Detection and Ranging)(LOLAS) which is aimed at the measurement of optical …
