AB: The Solar Occultation For Ice Experiment (SOFIE) was launched onboard the Aeronomy of Ice in the Mesosphere (AIM) satellite to measure polar mesospheric clouds (PMCs) and the environment in which they form. SOFIE measurements are used to retrieve vertical profiles of temperature, O3, H2O, CO2, CH4, NO, and PMC extinction at 11 wavelengths from 0.33 to 5 microns. SOFIE offers unprecedented sensitivity to PMCs, and is able to detect clouds that are from 30 to 100 times dimmer than could be observed by previous satellite and ground based instruments. SOFIE PMC measurements are used to characterize the altitude dependence of particle shape, ice mass density, and particle size. This work describes results using PMC measurements from the 2007 northern polar summer.
