Giant Cloud Condensation Nuclei (CCN) Impactor Raw Data
https://data.eol.ucar.edu/dataset/89.177

Summary
The NCAR/EOL/RAF Giant Cloud Condensation Nuclei Impactor (GNI) samples giant
aerosol particles. Slides were exposed in the free air stream onto uncoated
polycarbonate microscope slides. After exposure in the free air stream, the
slides were analyzed in the NCAR/EOL/RAF GNI slide chamber, using a
dual-optical microscope. Each slide was inserted into the humidified chamber
with a relative humidity of 89.8%. Each file (uncompressed) contains 350
images, but one needs to write the data out as a png file (or similar) in
order to see the images. Data are archived by date and are stored as .tar.gz
files. For a detailed description, see two manuscripts in preparation by
Jensen et al., available from the author.
