2DMAX-DOAS is a kind of device based on passive DOAS technology to realize automatic remote sensing of air pollutants in terms of horizontal and vertical distribution of trace gases in the whole and tropospheric atmosphere through a comprehensive manner by combining sun scattering spectra measurement at different azimuths and elevations and atmospheric transmission model.

KEY WORDS: Measuring instrument

BENEFITS:

Monitor horizontal and vertical distribution of vertical column concentration of tropospheric pollutant gases

Ground calibration for observing data of satellite

Monitoring transmission of pollutants at regional scale

Assisting in building pollution dispersal model
