Paper Abstract

As a fringe tracking stellar interferometer, the NPOI routinely determines time series of fringe motion and provides the only currently available simultaneous multi- baseline atmospheric turbulence data. We have used these time series to determine properties of atmospheric turbulence at the Anderson Mesa astronomical site near Flagstaff AZ. The shapes of the temporal power spectra imply an infinite outer scale. However, the total atmospheric power is significantly less than expected. This implies a very short outer scale, despite the shape of the spectra. The data are presented and discussed.
