In this paper, we present the results of an experimental analysis of atmospheric optical turbulence dynamics during the 2024 total solar eclipse (TSE). Changes in atmospheric optical turbulence strength throughout the entire TSE event were investigated by measuring the refractive index structure parameter (Cn2) and analyzing the corresponding short-exposure intensity scintillation patterns of a laser beam propagating over a 7 km near-ground atmospheric path. Data collection was conducted using a commercial large-aperture scintillometer and the recently developed AI-based TurbNet sensor, which enables high temporal resolution for Cn2 evaluation. The observed Cn2 parameter time evolution was characterized by the presence of dual turbulence quiescent (neutral stratification) phases and the generation of quasi-periodic oscillatory patterns during totality and for several minutes afterward.
