Second order closure integrated puff (SCIPUFF) model verification and evaluation study. Technical memo

This report summarizes a verification of the SCIPUFF model as descried in the draft report PC-SCIPUFF Version 0.2 Technical Documentation by Sykes et al. The verification included a scientific review of the model physics and parameterizations described in the report, and checks for their internal usage and consistency with current practices in atmospheric dispersion modeling. This work is intended to examine the scientific basis and defensiblity of the model for the intended application. A related task is an assessment of the model`s general capabilities and limitations. A line-by-line verification of the computer source code was not possible; however, the code was checked with a commercial code analyzer. About 47 potential coding inconsistencies were identified.
