摘要
In the past ten years workers of atmospheric physics and environmental science paid great attention to sounding of the planetary boundary-layer, because the atmospheric boundary-layer is closely bound up with human activities. For example, take-off and landing of aircrafts; launching of missiles, rockets and satellites; transport of air pollutants and improvement of weather forecast, etc., all relating to the distribution of atmospheric parameters (air temperature and wind, etc.) in the planetary boundary-
