An atmospheric water vapour profile was recorded using a UV Raman LiDAR located at Chilbolton Facility for Atmospheric and Radio Research (CFARR), during the Network for Calibration and Validation of EO data (NCAVEO) 2006 Experiment. The profile was recorded on 16th June 2006, one day before the ‘golden day’. The ground-based Raman LiDAR system at the CFARR transmits a high power Nd:YAG pulse laser beam vertically into the atmosphere at 355 nm wavelength. The LiDAR measures both elastic backscattering and water vapour profiles in the troposphere. Inelastic scattering of the laser radiation by molecules in the atmosphere, termed Raman scattering, is used to determine the atmospheric water vapour and temperature profiles. This dataset contains data for the raw (20s/7.5m) and processed (5min/22.5m) data in separate files. For further information on the parameters used during the data collection and the data's file format please see the dataset's metadata document in linked documentation.
