Education and career

edit

Penner has a B.A. in mathematics from the University of California Santa Barbara (1970), and an M.S. and a Ph.D. in applied mathematics from Harvard University (1972 and 1977, respectively).[1][2] Penner moved to Lawrence Livermore National Laboratory in 1977 and remained there until 1996, serving as a group leader from 1987 until her departure for University of Michigan in 1996.[1] At the University of Michigan, Penner was named the Ralph J. Cicerone Distinguished University Professor of Atmospheric Science in 2007.[1]

Penner has contributed[3] to multiple reports from the Intergovernmental Panel on Climate Change (IPCC), which was awarded the 2007 Nobel Peace Prize for its series of assessment reports.[4] Penner was the coordinating lead author for chapter 5 on "Aerosols, their Direct and Indirect Effects" within the 2001 Assessment Report 3, Working Group 1 (AR3 WG1), and one of 18 lead authors for the technical summary of that same report.[5] In 2007, she was one of 7 lead authors for chapter 9 on "Understanding and attributing climate change" (IPCC AR4 WG1 Ch9 2007).[6] In 2013, she served as a review editor for chapter 7 (Clouds and aerosols, IPCC AR5 WG1 Ch7 2013) and for the technical summary (IPCC AR5 WG1 Technical Summary 2013).[7] She was also one of the contributing authors for the 1995 IPCC report.[8]

Penner was the president of the Atmospheric Sciences Section of the American Geophysical Union from 2017 to 2018.[9] Since 2019 she has been the president of the International Association of Meteorology and Atmospheric Sciences.[10]

Research

edit

Penner's research interests focus on climate modeling, specifically the representation of aerosols in global climate models. Through her research, Penner has shown that the composition of aerosols impacts whether particles will increase or decrease global temperatures.[11] For example, her investigation into how biomass burning produces aerosols[12] concluded that smoke from burning tropical forests may cause cooling by an indirect effect because of the formation of droplets that reflect sunlight away from Earth's surface.[13] Within her climate models, Penner has examined the role of nitrogen compounds[14][15] and her research revealed that the nitric acid produced by supersonic aircraft (e.g., the Concorde) can lead to decreases in atmospheric ozone concentrations.[16][17] She has also defined the uncertainties associated with modeling indirect aerosol forcing,[18] including a consideration of differences across a suite of models.[19] This indirect aerosol effect impacts the amount of radiation received at Earth's surface[20] which is a function of how aerosol particles are formed.[21]
