Estimating hourly mixing depths from historical meterological data.

Abstract

The planetary boundary layer is defined as the layer of the lower atmosphere whose characteristics are directly influenced by the ground surface. In the atmosphere, turbulent mixing forms and maintains this layer; hence, the planetary boundary layer is also a mixing layer. Turbulent mixing can be either convectively or mechanically produced. A simple one-dimensional operational model is proposed to estimate reliable and realistic hourly mixing depths from routinely available upper air and surface data. - from Authors
