In April 1999, the U.S. Army Cold Regions Research and Engineering Laboratories (CRREL) gathered nearly 150 hours of cloud particle data in support of the Mt. Washington Icing Sensors Project (MWISP), a large field campaign that made diverse remotely sensed and in situ measurements. One of the main purposes of MWISP was to investigate the possibility of remotely detecting conditions that would be conducive for aircraft icing. CRREL used a Forward Scattering Spectrometer Probe (FSSP) and two Optical Array Probes (OAP) developed by Particle Measuring System Inc. (PMS) to collect cloud particle data from the summit of Mt. Washington during this period that would be useful in interpreting some of the remote measurements. In this study results obtained from an automated algorithm developed by Korolev and Sussman (2000) were used to produce a detailed summary of the data. The habits of four categories, dendrites, spheres, needles/columns, and irregulars were examined. Data that was partially missing was removed. The data was also summarized by different time periods. The habit percentages were normalized by the concentrations and current weather information was attached to the data. At the conference graphs and tables will be available which summarize these results.
