Abstract

The problem of reducing data from continuously recording ice nucleus counters is addressed. These instruments characteristically have large response times which make their data difficult to interpret. A statistical theory of instrument response is developed which parameterizes the response of these instruments and reconstructs an estimate of the true count-versus-time profiles. Data from two NCAR ice nucleus counters used on separate field projects are summarized to provide example response characteristics. Field calibration techniques for these NCAR counters are also described. Although intended for use on ice nucleus counters, the interpretation techniques are applicable to other continuously recording instruments having significant response times.
