UPDATES AND EVALUATION OF THE PX-LSM IN MM5
Citation:
Pleim, J E. AND A. Xiu. UPDATES AND EVALUATION OF THE PX-LSM IN MM5. Presented at MM5 Users Workshop, Boulder, CO, June 25-27, 2001.
Impact/Purpose:
This task objective is the development and improvement of state-of-the-science meteorology models and contributing process parameterizations for use in advanced air quality simulation model systems such as the Community Multi-scale Air Quality (CMAQ) modeling system and for other modeling studies and situations involving transport and dispersion of pollutants. Components of this work include: (a) improved meteorological and transport modeling, (b) improved meteorological modeling physics, (c) physical modeling of flows- building wakes, complex terrain, urban canyons, (d) modeling of transport and dispersion of specialized situations and (e) develop AERMOD (AMS/EPA Regulatory MODel).
Description:
Starting with Version 3.4, there is a new land surface model known as the Pleim-Xiu LSM available in the MM5 system. Pleim and Xiu (1995) described the initial development and testing of this land surface and workshop proceedings provided a basic description of the model and some evaluation (Pleim and Xiu, 2000). A recent journal article (Xiu and Pleim, 2001) presents a more detailed description of the LSM and its implementation in MM5 and further evaluation. This paper outlines some bug fixes, updates, guidance for use, and more evaluation.
