Desert Research Institute (DRI) cloud condensation nuclei (CCN) spectra
https://data.eol.ucar.edu/dataset/103.026

Summary
The DRI CCN (Hudson 1989) data (ASCE) provides number concentrations per
centimeter cubed normalized to surface pressure; i.e., these are mixing
ratios. 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. Documentation is in MSWORD .doc format.
