Brigitte Koffi (bkoffi) brigitte.koffi@lsce.ipsl.fr, Laboratoire des Sciences du Climat et de l'Environnement, France Sep 2011, The AeroCom database has been used to evaluate the vertical distribution of aerosols in 12 AeroCom I models using the CALIOP Aerosol Layer product. The methodology developped in this study will be adapted and integrated into the AeroCom evaluation tool, and applied to the evaluation of the AeroCom phase II simulations. Assess the impact of the models improvements, and further examine the models’ uncertainties and the potential limitations of the CALIOP data. For this purpose, a global monthly gridded (1°x1°) database is currently being built that will be also part of the AeroCom database. Koffi B. et al.

Cynthia Randles (crandles) Cynthia.A.Randles.1@gsfc.nasa.gov , NASA Goddard, USA Sep 2011, Analysis of AeroCom Radiative Transfer Experiment. The goal of the AeroCom Radiative Transfer Code Experiment is to assess the solar radiative transfer schemes in AeroCom global models without aerosols or clouds given a prescribed surface albedo and standard atmospheres (AGFL tropical and sub arctic winter O3 and water vapor profiles). This allows us to understand how each model treats Raleigh scattering, ozone absorption, and water vapor absorption. We also now include a clear-sky case with simplified aerosol optical properties (once scattering and once more absorbing) uniformly distributed in the lowest 2 km of the model.

Ping Yang / Bingqi Yi (bingqi.yi@tamu.edu) Department of Atmospheric Sciences, Texas A&M University, USA We are interested in estimating the effect of aerosol morphology on direct aerosol radiative forcing. Observations have shown solid evidence that aerosolcparticles are largely nonspherical. Most numerical models, however, treat aerosols as spheres using Mie theory to calculate their optical properties. We intend to look at AeroCom aerosol forcing products (especially for dust and black carbon) and compare them with results using our new optical property parameterizations. We would also use the AeroCom archive of observational dataset as the benchmark. The expected results will greatly improve our understanding of the uncertainty of aerosol particle shape in affecting radiation. Another focus of attention in our study will be on the interactions between aerosols and monsoon. Monsoon is known to play an important role in regulating the aerosol distribution, while aerosols inversely affect the monsoon intensity. We would investigate the performance of AeroCom models in the aerosol‐monsoon relationship in the global and regional scales.
