The Cloud Imaging and Particle Size (CIPS) experiment on the NASA mission Aeronomy of Ice in the Mesosphere (AIM) will
provide unprecedented coverage of Polar Mesospheric Cloud (PMC) morphology and microphysics. The AIM mission is scheduled
for launch in the fall of 2006. CIPS is one of three science instruments on AIM, whose primary objective is to reveal why
PMCs form and how & why they vary. CIPS will image the PMC cloud deck with 2 km resolution, and will measure the scattering
phase function of PMCs along with other microphysical properties such as particle size and water content. The instrument
consists of four wide angle cameras with a combined field of regard of 80 by 120 degrees. The camera field of view is
centered at the nadir. The clouds are imaged at 265 nm, taking advantage of the strong absorption characteristic of ozone at
this wavelength to enhance the contrast of the cloud scattering with respect to the background Rayleigh scattering. We will
discuss the instrument characteristics and the technique to derive cloud properties.
