Aerodyne Research, Inc. (ARI) has provided research and development (R&D) services to commercial and government clients working to solve national and international problems since 1970. Our R&D staff is organized into six technology centers which address such critical issues as global and regional environmental quality and development of clean and efficient energy and propulsion technologies. In conjunction with ARI's research activities, we also manufacture and sell high sensitivity, fast time response instrumentation for environmental air quality monitoring and atmospheric research. These instruments include Aerosol Mass Spectrometers (AMS), IR Laser Trace Gas Detectors (TILDAS), Chemical Ionization Time-of-Flight Mass Spectrometers (CIMS), Aerosol Chemical Speciation Monitors (ACSM), Particle Optical Extinction (CAPS PMex) monitors, and ultrasensitive nitrogen dioxide (CAPS NO2) monitors. ARI’s mobile laboratories provide services to collect data while in motion for plume characterization, area mapping or portable deployment for photochemistry and transport experiments. Our mobile laboratories are equipped with state of the art research and commercial instrumentation that can be tailored to fit a project’s need. ARI also designs, builds and utilizes remote sensing, surveillance, image processing, tracking and recognition systems for commercial and environmental applications and national defense.
