Aureole lidar: instrument design, data analysis, and comparison with aircraft spectrometer measurements.
A lidar system is developed to map extinction under the flight path of a P-3 aircraft. With a modified Cassegrainian telescope, signals from both wide and narrow fields of view are detected. The wide field-of-view detector senses the aureole signal generated by sea surface reflection and aerosol forward scattering. The narrow field-of-view detector senses the backscattering profile and the direct reflection off the sea surface. Optical depth and extinction profiles are derived from these signals. In comparisons made beween in situ aerosol-size spectrometer and lidar measurements, lidar profiles are smaller in magnitude but similar in shape to the spectrometer profiles.
