Abstract
We have measured the refractive index structure coefficient Cn2 at the VTT and GREGOR site for the past four years. We were using a laser scintillometer to measure free atmosphere Cn2 between the VTT and GREGOR towers, and anemometers on the GREGOR platform to measure localized seeing in the vicinity of the telescope. We present first results from these measurements and their comparison with seeing proxys derived from the GREGOR adaptive optics system GAOS.
