Desert Research Institute (DRI) cloud condensation nuclei (CCN) spectra
Listed in National Center for Atmospheric Research
The DRI CCN (Hudson 1989) data (ASCE) provides number concentrations per centimeter cubed normalized to surface pressure; i.e., these are mixing ratios.
Description
Data are recorded with a time stamp in each row. Time differences between adjacent rows are approximately equal to the integrated time of each measurement.
Data gaps are denoted by blank lines. Data gaps are caused by calibrations, cloud penetrations, or malfunctions. All data is contained in ASCII text files.
