Is given in a paper published in The Bulletin of the American Meteorological Society in 1994. A description of the ARM program and its measurement approaches Understanding atmospheric radiation and the influences on this radiation, especially Research in the ARM Program focused on (and in ASR continues to focus on) Much of the research of that program was (and in ASR continues toīe) focused on the influences of aerosols on atmospheric radiation, clouds, and climate.Īn overview of the issues pertaining to the climate influences of atmospheric aerosolsĪnd approaches to understanding the processes governing the life cycle of these aerosolsĪnd representing them in models is presented in a paper published in The Bulletin of the American Meteorological Society in 2007. (ARM) in 2009 these two programs were merged into the Atmospheric System Research (ASR) Program.įrom 2004 to 2009 I served as chief scientist of the Department of Energy’s Atmospheric Within CESD our research has been supported mainly by theĪtmospheric Science Program (ASP) and the Atmospheric Radiation Measurement Program Immediate concern to the United States Department of Energy, and much of the support for my research comes from the Climate and Environmental Sciences Division (CESD) within the Office of Biological and Environmental Research within that Department. (submicroscopic particles suspended in air).Īs these materials are introduced into the atmosphere largely in association withĮnergy-related activities, the environmental consequences of these emissions are of Of the planet, specifically including also the influences of atmospheric aerosols System to the increase of carbon dioxide (CO 2) and other so-called forcing agents, substances which change the radiation budget Interest has turned increasingly to understanding the response of Earth’s climate These substances are of concern from the perspective of human health,Īcid deposition, visibility reduction, and climate change. The principal substances of concern have been sulfurĪnd nitrogen oxides emitted into the troposphere as byproducts of fossil fuel combustion,Īnd their oxidation products, i.e., sulfuric acid and nitric acid and the salts of For much of my career my research has focused on the chemistry of Atmospheric Energy-Related
