Abstract

In order to characterized the vertical atmospheric structure at the Teide Observatory (Tenerife, Spain), we are using two different remote sensing technics: SODAR (SOund Detection And Ranging) and SCIDAR (SCIncitillation Detection And Ranging) at this astronomical site. We present in this work the preliminar results on the comparison of the simultaneous data from four consecutive nights in March 2007 using both technics. We have analized the SCIDAR C²_N profiles as well as an estimation of the structure constante of temperature function,C²_T, provided by SODAR. Such C²_T were compared to the simultaneous C²_N profiles from SCIDAR, determining a calibration factor between the measurements provided by SCIDAR and SODAR. As it was expected, our preliminary results indicate that this calibration factor is very sensitive to the variations of weather conditions.
