Title | | 'Statistical turbulence vertical profiles at the Roque de los Muchachos observatory and Teide observatory' |
Abstract | | A suitable characterization of the vertical turbulence distribution on a site should be based in statistical behaviour such as it is required for other parameters in site testing. We present the statistical results of the optical-turbulence profiles at the Roque de los Muchachos observatory and Teide observatory over annual periods. The data were obtained using the generalized SCIDAR technique at the 1m Jacobus Kapteyn Telescope and 1.5m Carlos Sanchez Telescope under unbiased statistical sample criteria because the campaigns were done monthly in the new moon nights. Statistically, most of the turbulence is concentrated close the observatory level (2400 m above sea level) with no more than two turbulent layers at higher altitudes. The temporal evolution of monthly statistical turbulence profiles indicates that the turbulence is concentrated at lower altitude layers during winter. We find a seasonal behaviour of turbulence structure at the ORM.
