Paper Abstract

The temporal fluctuations of the optical turbulence at different altitudes in the atmosphere are investigated. About 2400 C2N profiles, measured with a generalized scidar at the Observatorio Astronomico Nacional de San Pedro Martir, are used to determine the mean amplitude and characteristic time of the relative fluctuations of the optical turbulence in five atmospheric slabs. It is found that the saturation values of the relative fluctuations of the turbulence are 26%, 37%, 28% and 31% and the mean time for reaching 63% of these saturation values are 0.50, 0.20, 0.20 and 0.16 hours for the altitude slabs [2;4], [4;9], [9;16] and [16;21]km, respectively.
