Abstract

During the FATMOSE trial, day and night (24/7) scintillation data were collected for point sources at a range of 15.7 km. We used simultaneously our MSRT transmissometer (in scintillation mode) and a high resolution imager for the scintillation measurement. Because of the large source and receiver aperture, corrections were made for the effect of pupil averaging, determined by the transverse coherence length. In the paper examples are shown of scintillation spectra in comparison with Kolmogorov's -5/3 power law and of the log-intensity character of the scintillation. Attention is spent on the saturation effect, occurring in cases of small apertures. By using the multiband scintillation data, we were able to investigate the color dependence of scintillation, of which examples are shown. Measured scintillation data are also compared with predictions from our marine boundary layer based TARMOS model. It appears that the performance of these predictions is hampered by the inhomogeneity of the weather parameters along the path. In the paper several data series out of the large amount of available data are presented, covering a few consecutive days of data with examples of extremely low scintillation levels, probably occurring in cases of near-zero Air-Sea Temperature Difference along the total pathlength.
