Aerosol Magee Scientific instruments are deep underground to monitor diesel exhaust in mines and at the Base Camp of Mt. Everest to measure the regional pollution of remote locations. Our instruments are used at research stations from the Amazon Jungle to the Sahara Desert; from Spitzbergen to the South Pole. Our instruments are installed in agency stations from San Francisco to Shanghai, from Dublin to Delhi, and everywhere in between. They are used for fundamental research, air quality monitoring, environmental engineering, and other applications.
