AB: The CALIOP (Cloud-Aerosol Lidar with Orthogonal Polarization) instrument aboard the CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation) satellite has been acquiring data as part of the A-Train constellation of satellites since June of 2006. A complete level 1B data set and a limited set of level 2 data products have been publicly available since December 2006. As of December 2007, the level 2 data products have been augmented to include aerosol optical depths and extinction profiles. In conjunction, the MODIS-Aqua level-2 data set, MYD04, is readily available for essentially all days in orbit since June of 2002 and provides column integrated aerosol observations at a spatial resolution of 10x10km at nadir. In this paper we present comparisons of the standard MODIS-Aqua level-2 aerosol data to the initial release of the CALIPSO level-2 aerosol data set. As a first step towards investigating the cloud masking techniques for the two different instruments, we will show comparisons of the operational 500m-resolution cloud mask used in the MODIS-Aqua aerosol algorithm to single-shot CALIOP observations and the standard MODIS cloud mask product, MYD35, for the same scenes. Additionally, for a selected set of coincident and collocated measurements of several different aerosol types, we compare the optical depths retrieved by the two sensors.
