VAMMS Unit design Optimization of vehicle add-on mobile smoke monitoring system

Summary (Newest Update)

Background The United States Environmental Protection Agency (EPA), specifically the Office of Applied Science and Environmental Solutions, Applied Science and Environmental Methods Division (ASEMD) located at Research Triangle Park (RTP), NC, is seeking to enhance the Vehicle Add-on Mobile Monitoring System (VAMMS). This initiative aims to improve the design and data handling of VAMMS, reduce malfunctions, and enhance the overall user experience. The project is part of ongoing research efforts to characterize air quality impacts from wildland fire smoke. Work Details The contractor will be required to: (1) Furnish a written proposal for an improved VAMMS design; (2) Provide one alpha version of a modified VAMMS based on initial proposals; (3) Deliver three beta versions that incorporate EPA feedback into an optimized VAMMS; and (4) Provide a summary deliverable as specified in the Statement of Work. The technical specifications for the VAMMS include: - Detection of fine particulate matter (PM2.5) with a limit of detection of at least 3 mg/m³ and a range of at least 1500 mg/m³. - Detection of carbon monoxide (CO) with a limit of detection of at least 5 ppm and a range of at least 300 ppm. - Measurement capabilities for latitude, longitude, and elevation with an accuracy of at least 5 m. - Data recording using onboard memory storage with one-second time resolution. - Battery-powered operation with a minimum run time of 10 hours on a single charge. - A durable case for protection during shipping and use, small enough to fit in a vehicle passenger seat, weighing under 20 lbs., and equipped with an external isokinetic probe assembly for sampling air without vehicle modification.
