A lidar for measuring fluorescence from atmospheric aerosols was constructed with a third harmonic Nd:YAG laser, a 1-
m diameter telescope, and a 32-channel time-resolved photon counting spectrometer system. Fluorescence of aerosols in
the spectral range from 420 nm to 510 nm was studied with the excitation at 355 nm. The distribution of fluorescent
aerosols was studied in the time-height indications of the broad fluorescence. Type of the aerosols was identified from
simultaneous observation with a polarization lidar in the Asian dust and aerosol observation lidar network (AD-Net). It
was found that Asian dust and air-pollution aerosols transported from urban or industrial areas emit fluorescence.
Fluorescence efficiency was roughly estimated for these aerosols. The results suggest fluorescence measurements
combined with the measurement of microphysical parameters of aerosols using a multiple-wavelength Raman lidar or
high-spectral-resolution lidar will provide useful information for characterizing chemical properties of aerosols.
