[ABSTRACT]We have developed spectroscopic methods for continuous monitoring trace species in the lower atmosphere. Such kind of approach based on in-situ, long path length measurement is complementary to the conventional methods based on air sampling. First, differential optical absorption spectroscopy (DOAS) has been applied to simultaneously monitor aerosol and nitrogen dioxide, both being the most important air pollutants in the urban atmosphere. A pulsed xenon lamp equipped on a tall smokestack has been exploited as a light source of the DOAS measurement with an optical path length of 5.5 km. By analyzing the DOAS data with ancillary data from ground sampling, sunphotometer as well as weather data, aerosol behavior characteristic of the Chiba area has been revealed in relation to the regional wind system. Second, the long-path measurement using infrared light sources has demonstrated the capability of measuring atmospheric concentration of carbon dioxide, one of the most important greenhouse gases.
