Abstract

We have analyzed MDI data using time-distance autocorrelation function, in a high-frequency range above the acoustic cut-off frequency of the solar atmosphere. The MDI velocity, intensity and line-depth signals were looked at. The wave reflection rate at the photosphere has been found to be around 10 per cent for l = 125 and v = 6.75mHz. The result is compared with a previous measurement.
