STATEMENT OF WORK -- BACKGROUND: The Environmental Protection Agency in Taiwan (EPAT) has tested the air quality method known as CLImatology-PERsistance (CLIPER), which projects the current air polllutant concentrations using the average historical monitored mean concentations. Such method has so far yielded unsatisfactory results, mainly because the concentrations based on historical monitored data in the Taiwan area have shown very little correlation with the acautal current monitored concentrations. For this project, the California South Coast Air Quality Management District (SCAQMD) forecast approach is to beused to assemble a functional air quality forecast system for Taiwan. In general, this project would include 1) obtaining site-specific historical data, 2) analyze the data using multiple regression method to obtain an imperial correlation. Specifically, the model will be tested for the Taipei-Keelung air basin in Taiwan. At a minimum, the forecast results would include a 24-hour forecast capabilities for a set of air quality forecast parameters, including 24-hour forecast capabilities for a set of air quality forecast parameters, including 24-hour average PM10 and maximum hourly ozone concentrations. Documentation of the SCAQMD forecast approach have stressed the importance of modeler's understanding of adverse and episode air quality conditions in the area of interest. The contractor shall: Task 1 1a. Submit a work plan, within ten working days of receipt of this delivery order, that includes a detailed description of how each task (listed below) will be performed, a detailed budget (including a break-out of labor hours and other direct costs), and views on potential problems. Task 2 2a. Review the historical climatological and air quality data collected by the EPAT to better understand the synoptic and local climatology and other factors in the formation of pollution episode in Taiwan. These background documents are in Chinese. The contractor shall be able to communicate in Mandarin Chinese both verbally and in writing. 2b. Review the SCAQMD approach. This review process will involve detailed investigation of the procedures for acquiring climatological data, processing data, and computing model parameters. This task shall be conducted in parallel to the Task 2a. Task 3 3a. Determine the extent that the SCAQMD forecast approach would be applied to Taiwan, specifically the Taipei-Keelung area. The contractor shall identify the input parameters that are pertinent and applicable to the Taipei-Keelung air basin. In cases where a particular SCAQMD input parameter is rejected as being not applicable, the contractor shall determine whether an analogous parameter or a new parameter can be used. Task 4 4a. Perform a preliminary regression analysis that uses the applicable and analogous input parameters. The contractor shall include the following in its analysis: development of a statistical analysis program to rank the sensitivity and effectiveness of the candidate input parameters, preparation of input data files for the analysis programs, execution of the program with a set of meteorological scenarios agreed upon by the project manager of EPAT, generation of graphical display of the results, and summarization of the resulting statistical measures and ranking of the candidate parameters. Task 5 5a. Code and assimilate the best performing algorithm into Taiwan air quality forecast system. 5b. Compare modeling results with current monitored data. The comparative study shall be conducted for a time period agreeable to the EPAT project manager. 6. Deliverables 1. Work Plan2. Final report which discusses the applicability of the SCAQMD approach to the Taipei-Keelung air basin and summarizes the modeling results in detail shall be delivered to the EPA project officer prior to the end of the project period or at the completion of the project, whichever occurs first.
