  • Techniques for characterizing cloud condensation nuclel
    Patent number: 6529272
    Abstract: A cloud condensation nucleus spectrometer having a streamwise segmented condensation nucleus growth column. The condensation nucleus growth column includes alternating hot and cold temperature-maintaining segments arranged next to one another. The temperature difference between adjacent hot and cold temperature-maintaining segments increases from the input opening to an output opening of the condensation nucleus growth column to produce a supersaturation distribution that increases from the input opening to the output opening.
    Type: Grant
    Filed: November 20, 2001
    Date of Patent: March 4, 2003
    Assignee: California Institute of Technology
    Inventors: Richard C. Flagan, Patrick Yung-Shie Chuang
