AB: A prime mode of observation of the Aeronomy of Ice in the Mesosphere (AIM) mission is to make a variety of angular and multi-spectral measurements of PMC in the region of the terminator, where both CIPS (Cloud Imaging and Particle Size Spectrometer) and SOFIE (Solar Occultation for Ice Experiment) observe the same volume of space, separated by about 6 minutes in time. CIPS observes the same volume at a pixel size of 5 km for 7 separate scattering angles, thereby obtaining both the brightness (UV albedo) and scattering phase function. SOFIE observes the same volume at the limb in solar occultation at over a range of near-IR and UV wavelengths. Thus the combination of multi-spectral extinction, and UV scattering at multiple angles place unprecedented constraints on particle size distributions in PMC. We present the first results (northern summer, 2007) for the size and shape of mesospheric ice particles for some case studies from CIPS/SOFIE common volume measurements.
