Abstract

This dataset contains Raman Lidar data from four UK sites in the Met Office Volcanic Ash lidar network for the 15th and 16th October 2017 when ex-hurricane Ophelia passed to the West of the British Isles, bringing dust from the Sahara and smoke from Portuguese forest fires that was observable to the naked eye in the UK. The sites included are Camborne, Rhyl, Watnall, and Loftus.

The data files contain profiles for co-polar, cross-polar and Raman backscatter data. The data support the following publication: Osborne, M., Adam, M., Buxmann, J., Sugier, J., Marenco, F., and Haywood, J.: Saharan dust and biomass burning aerosols during ex-hurricane Ophelia: validation of the new UK lidar and sun-photometer network, Atmos. Chem. Phys. Discuss., https://doi.org/10.5194/acp-2018-695.
