Abstract
The performance of the Lidar Atmospheric Profile Sensor (LAPS) instrument for measurements of water vapor in the lower troposphere has been investigated. LAPS is an automated lidar system that measures water vapor from the vibrational Raman backscatter in the visible and in the ultraviolet wavelength range. We present a comparison of water vapor profiles measured with the lidar and balloon sondes as well as measured with the two lidar channels. With the UV channels it is possible to infer ozone profiles in the boundary layer. Data are presented that reveal the high variability of the water vapor in the boundary layer.
