A component of the FIRE Arctic Cloud Experiment was to collect in situ data in order to gain a broader understanding of the Arctic cloud microphysical properties and to utilize this knowledge to improve remote sensing analysis and radiation transfer models. The Cloudscope, a cloud probe instrument flown on the NCAR C-130, collected data on liquid drops, ice particles, and aerosol components present in the atmosphere on the neighborhood of the SHEBA observation site. The Cloudscope has a sample volume of approximately 30 cubic centimeters per second (a function of aircraft velocity) and detects particles ranging from 3 to 400 microns by capture and subsequent evaporation on a heated forward facing optical flat. Aerosols ranging from 3 to 50 microns in diameter have been detected in concentrations up to 4 per liter. Aerosol particles may be independent of liquid or ice and be important as possible nucleation sites in the stratus cold cloud layer. The evaporation / sublimation of cloud hydrometers has been observed to leave an occasional hygroscopic residue upon the collection substrate after the dehydration of the liquid or ice is complete. Aerosol concentration, spatial distribution, and characterization (contained in liquid drops, ice particles, or isolated) will be discussed in relation to CCN and cloud processes
