Abstract : The project was initiated to develop and test an instrument capable of measuring the activity spectrum of the cloud condensation nuclei (CCN) by simultaneously simulating a range of supersaturations encountered in cloud or fog formation. The design, fabrication, and testing of such an instrument has been successfully completed. This CCN spectrometer has definite advantages over all the CCN counters presently in use. A range of supersaturations, rather than only one supersaturation, can be produced and sustained at a given point in time. The spectrometer will be used for marine fog measurements.
