The Cloud Condensation Nuclei (CCN) Counter measures nucleied particle number concentration at different supersaturation. Rather than the traditional version of CCN counter where the supersaturation ratio is controlled by adjusting the temperature difference between coolers and thermocouples, in this version the supersaturation ratio is adjusted by scanning the sheath and sampling flow.
Please note this is QUALITY CONTROLLED, THOUGH STILL preliminary data THAT MAY BE SUBJECT TO FUTURE REVISION. This dataset contains ASCII text files listing particle number concentration under different supersaturation ratio using CCN mostly over investigator-defined sampling periods. It covers most of the ICE-T campaign period except RF13.
