The Cloud and Aerosol Particle Characterization (CAPAC) is an in situ airborne instrument package that measures cloud and aerosol particle properties. It includes three instruments: a Forward Scattering Spectrometer Probe model 300 (FSSP-300), a Two-Dimensional Optical Array Probe (2D-P), and a CAPAC video camera. It measures particle size from 0.3 micrometers to 6.4 millimeters and shape for particles between 40 micrometers and 6.4 millimeters in diameter. These measurements are used to determine particle size distribution, surface area, and water content in both ice and liquid form. CAPAC has a spatial resolution of 2 km at an aircraft speed of 200 m/sec and a temporal resolution of 0.1 Hz.
