[en] Meteorological observations and data collection from meteorological observatories were conducted in February, August and September, 1992 with the purpose of acquiring verification data for an atmospheric dispersion model. Observations were designed so as to acquire meteorological data over complex terrain under various meteorological conditions, such as snow covered ground surface in winter and land-sea breeze in summer. From the whole data ten periods of 24 to 48 hours which are suitable for model validation were selected. These periods cover wide variety of meteorological conditions from thermally induced circulations under a weak general wind condition to rather uniform and constant wind under a strong general wind condition. In the latter both strong westerlies of monsoon and easterlies of Yamase were observed. Vertical wind component was observed at a short interval in sodar observations. Mean values, standard deviations and spectra of vertical wind were analyzed to evaluate the reliability of sodar observation. The mean vertical winds reflect the terrain characteristics. It was concluded from the analysis of spectra that the standard deviation can be estimated by a simple arithmetic calculations of raw data. The dependency of the standard deviation on topography and stability was found to be qualitatively reasonable. Thus it was concluded that the mean value and the standard deviation of vertical wind from sodar can be used as a reference data of model verification. Although, more detailed analysis is essential in quantitative argument based on the spectral shape. (author)
