REMOTE SENSING APPARATUS AND METHOD FOR TROPOSPHERIC AEROSOL USING UV MAX-DOAS DURING HAZY CONDITIONS

摘要

PURPOSE: An atmospheric aerosol remote sensing apparatus using multi-axis differential optical absorption spectroscopy in a hazy state, and a method thereof are provided to efficiently and remotely monitor aerosol by using an O4 absorbing band with two UV wavelength spaces in a hazy state. CONSTITUTION: An atmospheric aerosol remote sensing method using multi-axis differential optical absorption spectroscopy is as follows. Atmospheric aerosol is sensed by using two ultraviolet rays, which have wavelength bands of 338-368nm and 367-393nm respectively, as the ultraviolet rays for sensing the atmospheric aerosol and by using a multi axis differential optical absorption spectroscopy device based on the wavelength bands.
