Workshop report on the Complex Terrain Model Development project (February 4-6, 1986)

The Complex Terrain Model Development project is being sponsored by the U.S. Environmental Protection Agency (EPA) to develop atmospheric dispersion models to simulate air pollutant concentrations in complex terrain that result from emission from large sources. In early October 1985, an initial version of the Complex Terrain Dispersion Model (CTDM) was delivered to EPA. A major step in the evaluation of CTDM was a workshop conducted in February 1986. Each participant was provided a diskette or tape of the CTDM code and a draft User's Guide and was asked to exercise the model to assess its overall effectiveness and validity.
