Abstract

The UV Raman lidar system at Chilbolton, England (51.1445N, 358.563E) is a high power, five channel Raman lidar system designed to make simultaneous measurements of attenuated lidar backscatter coefficient, humidity mixing ratio and temperature as a function of height. Two datasets are published on the BADC website: attenuated lidar backscatter coefficient and humidity mixing ratio. The attenuated backscatter coefficient is measured using the elastically scattered radiation. At this wavelength, elastically scattered light from both molecules and aerosols is detected. The humidity mixing ratio is measured using the much weaker Raman (inelastically) scattered light from water vapour and nitrogen molecules. Currently the temperature measurements are under development and data are not published.
