Testing a detailed biophysical parameterization for land-air exchange in a high-resolution boundary-layer model

Abstract

This study modifies the 1D PBL model of Zhang and Anthes (1982) to account more explicitly for the effects of a vegetation layer. New equations for the latent, sensible, and ground heat fluxes, reformulated in terms of vegetation parameters are substituted into the model. The model produces good agreement with observations over a wide range of conditions: for wet, high-vegetation conditions, and for dry, low-vegetation conditions in both the winter and the summer.
