The atmospheric boundary layer (ABL) height a fundamental parameter
characterising the structure of the lower troposphere. It is one of the important
parameters requested by different dispersion models as input data for forecasting air
quality. The aim of this chapter is to review various methods for the mixed layer height
estimate in a complex coastal valley area and compare them to achieve critical
awareness of their application. In this chapter, selected case studies of complex terrain
meteorology are presented.
