摘要：The performance of outdoor sound propagation models depends to a great extent on
meteorological input parameters. In an effort to improve speed and accuracy,
model output synthetic sound speed profiles (SSP) are commonly used depending on
meteorological classification schemes. In order to use SSP measured by RASS in
outdoor sound propagation models, the complex profiles need to be simplified. In
this paper we extend an investigation on the spatial and temporal
characteristics of the meteorological data set required to yield adequate
comparisons between models and field measurements, so that the models can be
fairly judged. Vertical SSP from RASS, SODAR wind profiles as well as mast wind
and temperature data from a flat terrain site and measured over a period of
several months are used to evaluate applicability of the logarithmic
approximation for a stability classification scheme proposed by the HARMONOISE
working group.
