AB: The CIPS (Cloud Imaging and Particle Size) instrument aboard the newly launched AIM (Aeronomy of Ice in the Mesosphere) satellite has been analyzed for the presence of gravity waves in the observed albedo. AIM is in a sun synchronous orbit with an equatorial local time currently centered near noon. CIPS is a nadir viewing CCD imager with a field of view of approximately 2000 km along track and 1000 km across track. The pixel size at nadir is 2 km by 1 km. CIPS observes albedo at 265 nm. At this wavelength and in the absence of PMCs (Polar Mesospheric Clouds), variations in ozone densities in the 40 to 70 km altitude region dominate the deviations in albedo which would be expected from an unchanging atmosphere across the field of view. Under the assumption that ozone is the sole driver for the albedo structure observed, high resolution 2D ozone structure has been inferred from the images. Initial analysis has indicated that the principle scale of ozone structure is typically on the order of 1000km. Typical amplitudes are on the order of 2% (4% peak to trough) in ozone density.
