Abstract
Atmospheric acoustic mini-sodar design characteristics, operating conditions and applications are described. Emphasis is given to the recent high space and time resolution applications in the field of the atmospheric boundary layer (ABL), such as wind energy, internal boundary layer, microclimate studies, etc.
Special mention is made on modern data processing and layer classification techniques, which in association with the high space resolution characteristics of the instrument make a powerful tool for detailed ABL research.
