May 6th, 2010 - Export of Asian pollution to the western Pacific

Quantifying pollution inflow and outflow over East Asia in spring with regional and global models by Meiyun Lin(Princeton U), Tracey Holloway (U Wisconsin), Greg Carmichael (U Iowa), and Arlene Fiore explores two high-resolution atmospheric chemistry models to examine the role of mesoscale versus synoptic scale processes in controlling pollution export from East Asia. Their results indicate the importance of rapid pollution venting through deep convection that develops along the leading edge of frontal system convergence bands. This transport mechanism is well captured in a high-resolution climate-chemistry model (WRF-Chem), but not adequately resolved in either of two coarse-resolution global models compared with aircraft observations of pollution lofting, suggesting a real need for high-resolution model studies of global pollution transport.

March 9th, 2010 - Identification of anthropogenic and natural dust sources using MODIS Deep Blue level 2 data

Identification of anthropogenic and natural dust sources using Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue level 2 data by Paul Ginoux (NOAA GFDL), Dmitri Garbuzov (Princeton U) and Christina Hsu (NASA) explores a new method to detect anthropogenic and natural dust sources from satellite data in the eastern part of West Africa. The anthropogenic contribution appears to be significant around the lake Chad, but the magnitude of these sources seem weaker than the natural sources, in particular relative to the Bodele depression.
