摘要：An acoustic tomographic system has been used to estimate area averaged wind and
temperature data within an area of 97 m × 12 m considering the dependence of
sound speed on meteorological conditions To obtain information about vertical
structure of meteorological data, eight sound sources and receivers were placed
in two different heights above the ground (0.5 m and 2.7 m). Spatially, the
acoustic measurements correspond to line integrated N2O concentration
measurements (98 m) using FTIR-spectrometers Taking stability of atmospheric
layering into account, acoustic tomographic measurements serve as basis for
estimating vertical fluxes of momentum and sensible heat.
