The Cloud and Water Vapour Experiment (CWAVE) was a measurement campaign at the CCLRC-Chilbolton Observatory; it was supporting associated with two EC FP5 projects, CLOUDMAP2 and CLOUDNET. A wide range of satellite and ground based instruments measured a variety of atmospheric properties ranging from cloud parameters to water vapour. In addition, the measurements coincided with the results from a reduced resolution Unified Model (UM) run by the Met Office. Access to such a data set allows unprecedented comparisons between observed and modelled data. This dataset contains time series of j(O1D) and j(NO2) measured by a diode array spectroradiometer (SR) and Spectroradiometer minute actinic flux measurements with respect to wavelength. The data was collected by the University of Leicester from the 23rd June to the 7th July 2003 during CWAVE 2003.
