- Description
- NAICS Code: 541710 The U.S. Environmental Protection Agency intends to negotiate a sole source, non-commercial purchase order with the University of California - Davis (UCD) to apply satellite data for three-dimensional modeling of PM2.5 formation and transport in San Joaquin Valley, California. Background: In 2005 EPA formed the EPA-GEO (EPA-Group on Earth Observations) committee in response to the Strategic Plan for the U.S. Integrated Earth Observation System (IEOS) developed by the Interagency Working Group on Earth Observations (IWGEO) of the Committee on Environment and Natural Resources (CENR). The IEOS Strategic Plan established a framework for U.S. agencies participating in the Global Earth Observation System of Systems (GEOSS) to link observations to societal benefits through an international effort to share and integrate Earth observation data. Though research conducted under the EPA-GEO Advanced Monitoring Initiative (AMI), EPA is providing key demonstration projects to support the U.S. Integrated Earth Observation System (IEOS) and the international Global Earth Observation System of Systems (GEOSS). The AMI projects are intended to demonstrate how a new "system of systems" can fill data gaps and affect the strength of information used for decision-making. AMI projects are intended as test beds to improve environmental health decision-making in specific contexts (e.g., geographic locations, demographic groups, and economic sectors) by advancing scientific understanding and showcasing approaches and outcomes suitable for broad EPA application (e.g., assessments, regulatory action, guidance, uncertainty, accountability, etc). The AMI project "Application of satellite data for three-dimensional monitoring of PM2.5 formation and transport in San Joaquin Valley, California" has been approved for funding from the AMI. This project will address the high concentrations of PM2.5 in SJV that significantly affect the public, environmental, and economic health of the area. Currently, point measurements from ground-based monitoring networks are used to validate model results, however these measurements are limited spatially. This proposal will integrate high resolution Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical depth (AOD), lidar aerosol vertical profile, and ground-based PM2.5 to derive surface PM2.5 measurements from MODIS AOD. This project will establish a three-dimensional PM2.5 data set for SJV, leading to more comprehensive model evaluation and information that may produce more effective, better targeted control strategies to reduce PM2.5. The project leads are EPA Region 9 and EPA Office of Research and Development (ORD). Collaborators on this project include NASA Langley, University of Maryland-Baltimore County, and California Air Resources Board (CARB). This project will be beneficial to the regulatory planning and technical community at the district, state, and federal level because it will exhibit the utility of satellite and lidar data for regional application in a high priority region in the western U.S., catalyzing the use of satellite data for regulatory applications. Specifically, the satellite and lidar data will provide greater spatial information of PM2.5 abundances in SJV at sufficient resolution to demonstrate the influence of local sources. The final products of this project will enable assessment of the existing PM2.5 monitoring network in SJV, model validation, comparison to results of previous intensive studies in SJV such as CRPAQS, and development of effective PM2.5 control measures. In the long term, this project may establish the need for additional intensive field campaigns or a ground-based lidar network in SJV. The results of this project will be made available for a potential "weight-of-evidence" analysis for the PM2.5 attainment demonstration in the SJV PM2.5 state implementation plan (SIP) and may be incorporated into the SIP in a future review. The role of the UCD in this project is to build upon existing photochemical model results previously developed to support CARB's SIP. The contractor will produce a detailed comparison of high resolution satellite aerosol optical depth to model results of aerosol optical depth for several seasons in 2000. Since this project will use satellite data already collected by NASA, the plan will not cover satellite data collection, retrieval, and technical processes taking place in that agency's quality system. The following details the SOW tasks: Task 1: Obtain Community Multiscale Air Quality (CMAQ) model outputs for several parts of year 2000 from ARB. Calculate model derived aerosol optical depths using the initial method already developed [e.g., Roy et al., 2005]. Compare satellite-derived AOD with modeled AOD for available satellite results. This type of comparison will help provide quantitative information on the accuracy of model results for PM2.5 in SJV, both below and above the boundary layer. Task 2: Provide modeling meteorological results for the winter 2000 period to other collaborators (i.e., NASA Langley and EPA) for the winter climatology characterization of the San Joaquin Valley (SJV). Assemble meteorological measurements in SJV, including CRPAQS data base and CARB monitoring sites, wind profiler, cloud measurements, boundary layer measurements, weather service (Conis), CALIPSO cloud data (if available), and NOAA meteorology data. Task 3: Provide modeling aerosol results for the winter 2000 period to other collaborators (i.e., NASA Langley and EPA) for the winter particulate matter characterization of the San Joaquin Valley (SJV). Assemble air quality measurements in SJV from sources such as the CARB ground-based measurement network and possibly from the AERONET sites in SJV. Task 4: In conjunction with collaborators at NASA and EPA, develop mathematical/statistical computer routines for data comparison and quantitative analysis of ground-based PM2.5, lidar aerosol, and satellite aerosol optical depth data that will be collected during December 2006-January 2007. Task 5: Contribute results to the project's quarterly reports for AMI, prepare a document summarizing the analysis conducted during this project, and prepare one journal article containing significant findings. EPA believes that UCD is the only source capable of providing the required services due to their unique experience and in-depth knowledge of photochemical gird models and experience in modeling particulate matter in the San Joaquin Valley, CA. The circumstance permitting Other than Full and Open Competition Justification is FAR 6.301-2, "Only one responsible source and no other supplies or services will satisfy agency requirements". The period of performance of the order is expected to be from October 1, 2006 through September 30, 2007. All interested parties who believe they can provide the required services should fully explain their capabilities and qualifications in writing within 15 days from the date of this announcement. The intent of this synopsis is to determine if any source(s) exist and, therefore, no RFQ is available. Consequently, any response(s) failing to provide the aforementioned data but instead choosing to merely submit a routine letter requesting a copy of the RFQ will not be honored. Submit your response to the U.S. Environmental Protection Agency, RTP Procurement Operations Division (E105-02), Attn: Rebecca Clausen, Research Triangle Park, NC 27711 or e-mail clausen.rebecca@epa.gov.
