We present results from a new retrieval algorithm (v4.20) applied to measurements from the Aeronomy of Ice in the Mesosphere (AIM) Cloud Imaging and Particle Size (CIPS) instrument. CIPS measures solar scattering at 265 nm by polar mesospheric clouds (PMCs) to infer cloud presence, albedo, particle radius, and ice water content. Images covering the summer polar region with 5-km horizontal resolution have been obtained on a daily basis since the 2007 northern hemisphere PMC season (a total of seven PMC seasons in both hemispheres). Measurements at each location are made over a range of scattering angles, enabling separation of cloud signals from Rayleigh scattering by the background atmosphere. The new algorithm involves a fundamentally different approach to distinguishing between the PMC and Rayleigh scattering signals. In this presentation we will give an overview of the retrieval approach and will discuss sensitivity studies that have been performed to quantify its uncertainties. Results from v4.20 will be compared to results from the previous version (3.20). We will show that the improved background subtraction yields images with more distinct features and higher fidelity, and enables retrievals to be performed at lower latitudes than previously possible. We will also describe statistical results comparing PMC variations within and between different seasons.
