Abstract |
The Complex Terrain Dispersion Model Plus (CTDMPLUS) is a refined air quality model for use in all stability conditions for complex terrain applications. It contains the technology of the original Complex Terrain Dispersion Model (CTDM) for stable and neutral conditions, but also models daytime, unstable conditions. The model makes use of considerable detail in the terrain and meteorological data (as compared to current EPA regulatory models) and requires the parameterization of individual terrain features, thus considering the three-dimensional nature of the interaction of the plume and terrain. |
Supplementary Notes |
System: IBM PC or compatible; MS DOS operating system. Language: FORTRAN77 and Pascal. Attempts to run the modeling system without a math co-processor will cause a runtime error number of 4001. Supersedes PB88-161682 and PB88-162169. |
Availability Notes |
The software is contained on one 1.2M, 5 1/4 inch diskette, high density. File format: ASCII. Price includes documentation, PB90-243809. |
