- Description
- The U.S. Environmental Protection Agency (U.S. EPA) has a requirement for Quantitative Transport Bias Analysis (QTBA) Hybrid Recptor Model Development. The QTBA model requires updating and enhancement for application to the STN PM2.5 data and source contribution estimates from receptor models. The HY-SPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectories) model developed by NOAA's Air Resources Laboratory (Draxler, 1997) can provide advanced back-trajectory input data for QTBA. In addition, output from meteorological models such as the Eta Data Assimilation System (EDAS) are being archived at higher spatial and temporal resolution, allowing for improved trajectory calculations. The QTBA model algorithms need to be refined to take advantage of contemporary trajectory and meteorological data, and to provide improved estimates of trajectory uncertainties for region-scale source area identification. Further model development is also needed to account for the complexity of source contributions for urban monitoring sites. The QTBA model could be improved to better distinguish local from regional source impacts by reducing the model domain and grid size from the current regional-scale domain comprised of the entire eastern U.S. Higher resolution trajectory data using fine-scale meteorological model output would also be required to allow enough spatial resolution for QTBA to quantify local source impacts. Therefore, the main purpose of this contract is to update and enhance the existing QTBA hybrid receptor model that incorporates trajectory uncertainties in estimates of source area contributions. An improved QTBA model will allow EPA and State and Local air pollution control agencies to more accurately identify and quantify regional-scale source areas contributing to PM concentrations at STN and IMPROVE network sites. Optional tasks are included to provide a larger database of back-trajectory data for STN sites, a website for QTBA model user access to the trajectory database, and additional refinement of the QTBA model to provide capability for identifying source areas at the urban-scale. EPA anticipates the award of a fixed price contract. NAICS Code 541690 applies with a small business size standard of $5M in average annual receipts over the last three years. A Draft copy of the Statement of Work (SOW) will be posted on website: http://www.epa.gov/oam/rtp_cmd/. A copy of the Request for Proposal (RFP) with SOW will be posted on or about the date the RFP is issued. Any supporting documentation and/or relevant information (if applicable) concerning this procurement will be posted on website: http://www.epa.gov/oam/rtp_cmd/. The RFP is expected to be issued approximately on July 12, 2004 as full and open competition. Proposals will be due approximately 30 calendar days after issuance of the RFP and it will be your responsibility to frequently check the same site where the RFP is posted for any amendments.
