IMPLEMENTATION AND EVALUATION OF PRIME IN AERMOD

摘要

The U.S. Environmental Protection Agency (EPA) recently proposed changes to the air quality modeling guidelines to replace the ISCST3 model with the AERMOD model (Cimorelli, et al, 1998) for applications where building downwash is not important, and to replace ISCST3 with ISC-PRIME (Schulman, et al, 2000) for applications where downwash is important. In response to public comments, EPA has incorporated the PRIME building downwash algorithms into the AERMOD model. This paper describes the implementation and developmental evaluation of the AERMOD model with PRIME downwash algorithms. The implementation of PRIME in AERMOD was guided by the goal of keeping the PRIME downwash algorithms as intact as possible, while incorporating the improved meteorology of the AERMOD model.
