Abstract

We present measurements of the atmospheric refractive index structure parameter C_n² and the inner scale l_o made with a SLS-20 scintillometer manufactured by Scintec GmbH. The measurements are compared to measurements of scintillation made with a simple in-house built scintillometer and to C_n² derived from measurements of C_T² made with differential temperature probes. We found that the combination of l_o and C_n² data provided by the SLS-20 allowed us to calculate the log-amplitude variance of the scintillation measured with the in-house scintillometer with good agreement. Poor agreement was found between the SLS-20 and temperature probe C_n² data primarily because of the limited frequency response of the probes.
