| Abstract |
The paper describes the current state of EPA's Complex Terrain Disperson Model (CTDM), which has been under development during the past five years. The CTDM employs the concept of a dividing streamline height (a function of wind and temperature profiles), below which plume segments pass round the sides of a hill and/or above which they pass up and over the top. The model is currently constrained to simulate concentrations on the windward side of isolated terrain. The paper includes a comparison of CTDM concentration estimates with concentrations observed during a recent tracer study from a power plant in the Sierra-Nevada Mountains. |
