The paper describes the Particle Data Reduction (PADRE) system, developed to attract high-quality size-mass distribution data for the Fine Particle Emissions Information System (FPEIS), a component of EPA's Environmental Assessment Data Systems (EADS). FPEIS is the heart of a comprehensive information system for fine particles suspended in gas streams. PADRE users interactively store, edit, reduce, and analyze observed impactor data from anywhere in the Continental U.S., with no computing expenses. Extensive data quality checks and computer-prompted, user-directed program operations are featured to assist users in obtaining meaningful information a few minutes after impactor data are entered. Design goals, program operation, and sample sessions are discussed, as well as plans for future system development.
