over Southeast Asia has been associated with rapid economic growth and the use of “dirty” energy, while decreases in aerosol over Europe are associated with clean-air legislations and the dissolution of the former Soviet Union. Decreases seen over North America are consistent with decreases in industrial emissions as a result of enactment of similar clean-air legislation ( Mishchenko and Geogdzhayev 2007 ; Zhao et al. 2008 ; Hsu et al. 2012 ). Additional analysis using surface-based Aerosol

% were either mainly of crustal origin with little biological content or potentially large sea spray aerosols, which could not be distinguished in our study because isotope data are not available for this period. g. INPs at the Jungfraujoch in comparison to DeMott et al. (2010) Figure 10a shows an overview of INP concentrations at relative humidities above water saturation from several field and airborne studies in North America, Brazil, and over the Pacific from DeMott et al.

the SML collected in the North Atlantic were smaller than 0.2 μ m. DeMott et al. (2016) found elevated numbers of INPs associated with SSA generated by the frit technique, known to favor production of smaller particle sizes (mode diameter less than 0.1 μ m), suggesting that the mode diameter of INPs may be sub-0.1 μ m or that the frit technique preferentially transferred smaller ice nucleating material to the aerosol phase. Diverse trends in the abundance of INPs active at different

information about the impact of aerosol type on invigoration. In the northern part of South America and in central Africa, where biomass burning dominates, the positive correlation between CTH and aerosol loading shows a clear evidence of invigoration. A positive correlation is also seen over the Indonesian landmass, where pollution is heavy. Almost no correlation can be seen over the downwind region of North Africa, where dust dominates. Note that AOD data are not available for North Africa and the

–Cloud–Climate (ACC) symposiums that have been held at the American Meteorological Society (AMS) annual meeting. A special collection of papers has been created on aerosol–cloud–precipitation interactions in the Journal of the Atmospheric Sciences that are based on presentations from the recent ACC symposiums. This review also serves as an introduction to the special collection. We will concentrate on ACI with ARI discussed jointly since in the real world ACI and ARI are not separated, and many studies looked

a stretched vertical resolution, which is finer close to the ground (about 50 m) and coarser aloft (about 400 m above 14 km). North American Regional Reanalysis (NARR) is used as the initial conditions and lateral boundary conditions, which are updated every 3 h. Fig . 1. Two-way nested configuration of the modeling domains. Domain 1 (d01) has a size of 900 km × 900 km with a horizontal grid spacing of 9 km, centered at the SGP central facility (36.5934°N, 97.5113°W).
