Symposium on Mesoscale to Microscale Coupling Methods
to Meet the Wind Industry’s Needs
Sept. 14, 15:  9:00 - 1:00 MDT

Purpose: To make the wind industry and others aware of the tools that have been developed by the DOE-sponsored Mesoscale-to-Microscale Coupling (MMC) team, discuss issues to consider in coupled modeling, describe best practices based on our experience, and describe lessons learned. We define MMC as coupling mesoscale models to large-eddy simulation models (LES).
