The Evaluation and Assessment of UNAMAP is a study to determine how best to improve the usefulness and availability of the UNAMAP air pollution dispersion models. The report describes a plan for implementing a series of recommended improvements to the UNAMAP program. It also describes the earlier parts of the study upon which the plan is based. The study consisted of a technology assessment followed by data collection and analysis which were used to develop the strategy and the specific improvements contained in the plan. The overview includes a summary of the data collected during the study, and the conclusion, drawn from analysis of that data. The analysis indicates that improvements to UNAMAP are needed in the areas of: (1) model accuracy; (2) model documentation; (3) user support; (4) data collection; (5) data input; and, (6) computer compatibility. The report describes a plan which is based on a strategy that is consistent with the longterm objectives for UNAMAP. The report contains a strategic framework for improving UNAMAP. The strategic framework guides the implementation and strikes a balance between the goals of advancing dispersion modeling research and transferring technology to the public. Included in the plan is a set of ten specific recommended improvements which are described and broken into specific tasks. Estimates of time and cost required to implement each improvement are given at the task level. Finally, the recommended improvements are grouped into three phases. A schedule is presented at the task level for the five recommended improvements in Phase 1.
