Atherton Postdoctoral scholars: J. Dignon, C. Chuang, C. Liousse, C. Price, D. Erickson MAJOR ACCOMPLISHMENTS Joyce Penner is a leading expert on the interactions of chemistry, aerosols, and their effects on the climate system and has played an active role in recognition of the effect of aerosols on climate, organizing several meetings on these topics including, most recently, the 5th International Conference on Carbonaceous Particles in the Atmosphere. Dr. Penner's work on aerosols began in early 1983, when Turco and co-workers as well as Crutzen and Birks pointed out the possible large climate effects of smoke aerosols from fires initiated in the aftermath of a large-scale war. Dr. Penner developed models to study the processes of coagulation and aerosol scavenging by clouds in the early smoke plumes (Penner, et al., 1986; Penner and Porch, 1987; Edwards and Penner, 1988). The inclusion of these processes both altered the total amount of smoke injected into the free troposphere and its optical properties. Incorporation of these processes could, therefore lead to large uncertainties in the evaluation of the effects of a nuclear war (Penner, 1986). Later evaluations of the effects of nuclear war, recognized the importance of including these effects (Ghan et al., 1989). Dr. Penner's work has also had a major influence on the study of tropospheric chemical cycles. She developed a simplified treatment for the chemical interactions within the nitrogen cycle in the troposphere and used a three-dimensional model together with comparison to observations to place constraints on the sources of nitrogen in the troposphere, especially that from lightning. Estimates for the lightning source of NOx have varied from 2 to over 100 Tg, but Dr. Penner's work was able to constrain it to the range 2 to 10 Tg (Penner et al., 1991). In the continuing development of three-dimensional chemical transport models for the troposphere, Dr. Penner has also played a role in promoting 3-dimensional model intercomparison studies. These studies are aimed at understanding the adequacy of transport and scavenging processes in 3-D models. Dr. Penner participated in 2 model intercomparison workshops and helped to organize the World Climate Research Program Workshop on the Transport and Scavenging of Trace Constituents by Clouds in Global Models in 1995. After Charlson and co-workers proposed a link between ocean emissions of dimethyl sulfide and cloud albedo, Dr. Penner also began work to understand the sulfur system in the troposphere and its relation to climate and climate change. Schwartz published a challenge to the Charlson hypothesis in 1988, based on an analysis of sulfate from anthropogenic sources mainly in the Northern Hemisphere and observations of cloud albedo. Penner, together with Ghan and Taylor, challenged Schwartz's simplified analysis (Ghan et al., 1989). Based on more complete chemical box-model studies with Kreidenweis et al. (1991), Dr. Penner developed simplified treatments for the sulfur cycle within a global climate model and used this model to quantify the climate forcing and climate response from anthropogenic sulfate aerosols (Taylor and Penner, 1994). This work has had a major effect in understanding how climate has changed over the last hundred years (Santer et al., 1995; 1996; IPCC, 1995). In addition to her work on the sulfate aerosol system, Dr. Penner began studies of climate forcing from aerosols produced in biomass burning (Penner et al., 1992) as well as absorbing black carbon aerosols from fossil fuel burning (Penner et al., 1993) and organic aerosols (Novakov and Penner, 1993; Liousse et al., 1996). These effects are now recognized as important to include in estimates of the total forcing over the last 100 years (IPCC, 1995). Dr. Penner's research continues to attempt to add more realistic estimates for the effects of aerosols in climate models and has recently been extended to include realistic methods for treating the indirect forcing by anthropogenic sulfate aerosols (Chuang and Penner, 1995; Chuang et al., 1997; Lohmann et al., 1999; Penner et al. 1999; Penner and Rotstayn, 2000) as well as both direct and indirect forcing estimates for carbonaceous aerosols (Penner et al., 1998; 1999; Grant et al., 1999).

Specific interests include (i) the role of atmospheric aerosols in biogeochemical cycles of N, S and other elements, (ii) how aerosols-sea salt aerosols in particular-affect marine boundary layer photochemical processes, and (iii) implications of the above for climate forcing. Dr. Pszenny began his independent research career with NOAA in the mid-1980's when the notion arose that aerosols produced from reduced sulfur species of marine biogenic origin may be part of a climate regulation mechanism. He was among the first to investigate the size distribution of aerosol sulfur in the Antarctic and equatorial Pacific marine boundary layers. He co-organized a major experiment in the North Atlantic in 1988 among whose results were (i) a first assessment based on measurements of the roles of dimethylsulfoxide and dimethylsulfone in the atmospheric S cycle, (ii) evidence that a significant fraction of sulfur dioxide is converted to sulfate in sea salt aerosols, and (iii) evidence of "unexplained" chloride loss from sea salt aerosols. Since then he, colleagues from the University of Virginia, and others have sought to test the hypothesis that these chloride deficits result from release of chlorine species much more reactive than hydrogen chloride from sea salt aerosols. This work included development of an improved experimental technique for estimating aerosol pH. Since 1993 Dr. Pszenny's principal activity has been to serve as executive officer for the International Global Atmospheric Chemistry (IGAC) Core Project of the International Geosphere-Biosphere Programme (IGBP). In this role he has helped to frame discussions of the future course of global atmospheric-biospheric chemistry research, how this research will be coordinated internationally and interfaced with that of other elements of the IGBP, and how its findings will improve understanding of key biogeochemical cycles and reduce the scientific uncertainties that hinder prediction of climate change. Dr. Pszenny has published more than 30 peer-reviewed scientific papers, 8 as lead-author. He has also authored several newsletter articles describing IGAC accomplishments and edited a number of IGAC planning documents.
