Our primary interest is to find the most realistic, robust, practical, and economical way to represent the effects of humidity on stomatal conductance in a mesoscale meteorology and air quality model system. In particular, the authors have developed a land surface model, coupled to the Penn State/NCAR Mesoscale Meteorology model (MM5) and the Community Multiscale Air Quality (CMAQ) model to simulate both evapotranspiration and chemical dry deposition. This paper describes a series of modeling experiments where several parameterizations of stomatal response to humidity are studied. The test code is simply extracted from the 3-D grid model so that the results are directly applicale to the mesoscale modeling system.
