NRC Convair 580 Aerosol Data




Aerosol measurements from 5 instruments operated by the National Research Council of Canada on-board the NRC Convair 580 aircraft during ICICLE (In-Cloud ICing and Large-drop Experiment). These include measurements of the temporal and spatial variability of aerosol diameters, concentration, composition and activation properties. CCNc,UHSAS,CPC,and SP2 were installed in the cabin and sampled the interstitial and residual aerosols through a heated inlet installed on top of the fuselage. For a number of flights, an additional wing-UHSAS was installed. The CCNc was operated with a constant pressure inlet for most of the time at a fixed supersaturation for high spatial resolution and part of the time in a supersaturation scanning mode to retrieve the CCN spectra. The data are provided in a NetCDF format together with an aerosol data guide and html quick-looks of selected variables for easier browsing.
