TL;DR: In this paper, two intense dust storms were generated over the Gobi desert by springtime low-pressure systems descending from the northwest, and the windblown dust was detected and its evolution followed by its yellow color on SeaWiFS satellite images, routine surface-based monitoring and through serendipitous observations.
Journal ArticleDOI
In situ detection of biological particles in cloud ice-crystals
Kerri A. Pratt,Paul J. DeMott,Jeffrey R. French,Zhien Wang,Douglas L. Westphal,Andrew J. Heymsfield,Cynthia H. Twohy,Anthony J. Prenni,Kimberly A. Prather +8 more
TL;DR: In this paper, aircraft-aerosol time-of-flight spectroscopy measurements of ice residues indicate that biological particles trigger ice formation in high-altitude clouds, which is one of the largest remaining sources of uncertainty in climate change projections.
Journal ArticleDOI
A multidimensional model for aerosols - Description of computational analogs
TL;DR: The numerical algorithms used to simulate the advection, diffusion, sedimentation, coagulation and condensational growth of atmospheric aerosols are described and the continuity equation is developed in a generalized horizontal and vertical coordinate system.
Journal ArticleDOI
Global Monitoring and Forecasting of Biomass-Burning Smoke: Description of and Lessons From the Fire Locating and Modeling of Burning Emissions (FLAMBE) Program
Jeffrey S. Reid,Edward J. Hyer,E. M. Prins,Douglas L. Westphal,Jianglong Zhang,Jun Wang,Sundar A. Christopher,C. A. Curtis,Christopher C. Schmidt,D.P. Eleuterio,Kim Richardson,J.P. Hoffman +11 more
TL;DR: An overview of the FLAMBE system is given and fundamental metrics on emission and transport patterns of smoke are presented and it is demonstrated that MODIS optical depth data assimilation provides significant variance reduction against observations.
Journal ArticleDOI
Long‐range transport of Siberian biomass burning emissions and impact on surface ozone in western North America
Daniel A. Jaffe,Isaac T. Bertschi,Lyatt Jaeglé,Paul C. Novelli,Jeffrey S. Reid,Hiroshi Tanimoto,Roxanne Vingarzan,Douglas L. Westphal +7 more
TL;DR: In this paper, the authors used the NRL Aerosol analysis and prediction system (NAAPS) model to forecast the transport of smoke from Siberian biomass fires, which resulted in enhancements in summer background CO and O3 of 23-37 and 5-9 ppbv, respectively, at 10 sites in Alaska, Canada and the Pacific Northwest.
