The acoustic travel time tomography is presented as an experimental technique for concurrently monitoring of spatially averaged meteorological quantities and the determination of the atmospheric excess attenuation of sound. This ground-based remote sensing technique uses the nearly horizontal straight-line propagation of sound waves in the atmospheric boundary layer up to several hundred meters. By measuring the elapsed time and the modification of the amplitude of the transmitted signal the acoustic velocity along the propagation paths as well the attenuation of the signal can be determined assuming a straightray sound propagation. This enabled us to determine meteorological data, as the temperature and wind speed, and the influence of the atmospheric conditions on the sound attenuation at the same time. The acoustic measuring system, together with several reference measurements, was applied during a field campaign in autumn 2004. In a meadow, a cross with several sound sources and receivers with an extension of roughly five hundred meters was arranged to measure the travel time and the relative amplitude of sound signals. The main objective of the field experiment was to investigate the spatial structure and statistical characteristics of the wind speed and temperature fluctuations in the surface layer with the space-time scales inherent to atmospheric internal gravity waves. These investigations should lead to a better understanding of the role of the internal gravity waves in the dynamics and turbulent regimes of the stable atmospheric boundary layers.
