Abstract : At the end of May the CCN spectrometer and calibration equipment were transported to Monterey for the field project The equipment operated successfully for most of the time on 11 of the 12 research flights. For most of the time the CCN spectrometer directly monitored the ambient CCN spectrum. Occasionally, the sample aerosol was heated to obtain particle volatility. Sometimes the aerosol was size classified to obtain the relative solubility of the CCN. During some of the in-cloud passes the CCN spectrometer monitored the residue from the cloud droplets from the counterflow virtual impactor (CVI) which allows a precise determination of the CCN that are actually within the cloud droplets.
