Abstrakt: During the 2017 Ozone Water Land Environmental Transition Study (OWLETS), the Langley Mobile Ozone Lidar system utilized a new small diameter receiver to improve the retrieval of near-surface signals from 0.1 to 1 km in altitude. This new receiver utilizes a single 90 degree fiber-coupled, off-axis parabolic mirror resulting in a compact form that is easy to align. The single reflective surface offers the opportunity to easily expand its use to multiple wavelengths for additional measurement channels such as visible wavelength aerosol measurements. This unique added capability allows for near-field analysis of ozone profile concentrations, enabling the study of near-surface pollution dynamics. Results compare the performance of the receiver to both ozonesonde and in-situ measurements from a UAV platform, validating the performance of the near-surface ozone retrievals.
