摘要：

In this article I describe a site survey facility, which measures the signals of the solar equivalent of a Differential Image Motion Monitor (S-DIMM) and of a six element linear array of solar scintillometers. Combining the S-DIMM r(o) and scintillometer sigma(I) observations allows the determination of the fractions of the seeing in the free atmosphere and in the ground/lake layer. From the scintillometer array observations C-n(2)(h) is determined for heights corresponding to the first similar to500 m along the line-of-sight. With minor changes this seeing monitor can also be used for other extended objects like the Moon and planets.
