Through these actions, in particular those under the UNECE Convention on Long-range Transboundary Air Pollution, air emissions were substantially reduced, and ecosystem impacts decreased. Widespread scientific research, long-term monitoring, and integrated assessment modelling formed the basis for the policy agreements. In this paper, which is based on an international symposium organised to commemorate 50 years of successful integration of air pollution research and policy, we briefly describe the scientific findings that provided the foundation for the policy development. We also discuss important characteristics of the science-policy interactions, such as the critical loads concept and the large-scale ecosystem field studies. Finally, acid rain and air pollution are set in the context of future societal developments and needs, e.g. the UN's Sustainable Development Goals. We also highlight the need to maintain and develop supporting scientific infrastructures.}, number={4}, journal={AMBIO}, author={Grennfelt, Peringe and Engleryd, Anna and Forsius, Martin and Hov, Oystein and Rodhe, Henning and Cowling, Ellis}, year={2020}, month={Apr}, pages={849–864} }

Since the 1970s, the USDA Forest Service Forest Inventory and Analysis (FIA) Program has assessed fusiform rust incidence on its network of ground plots in 13 states across the southeastern United States. Through analysis of the FIA data, we found that current fusiform rust incidence varied by state, forest type, and stand origin and that across all stand ages, rust incidence was approximately equal in planted and natural stands of loblolly pine but was higher for planted versus natural stands of slash pine. Decreases in rust incidence over the last 30–40 years were evident in young planted loblolly pine stands but not in young planted slash pine stands. Results for slash pine were surprising, and the reasons remain unclear but one reason may be planting stock origin, which was unknown and may be highly variable in rust resistance. These analyses of FIA rust incidence data also were used to update the original rust disease hazard maps published by Starkey et al. (1997).}, number={4}, journal={JOURNAL OF FORESTRY}, author={Randolph, KaDonna C. and Cowling, Ellis B. and Starkey, Dale A.}, year={2015}, month={Jul}, pages={381–392} }

Seed lots from more than 15,000 selections of slash and loblolly pines have been evaluated for genetically-controlled resistance to fusiform rust and other diseases including pitch canker, dogwood anthracnose, and brown spot needle blight. The screening system uses a greenhouse-based artificial inoculation system with controlled density of inoculum from geographically diverse sources of the rust pathogen. Results are completed in 6–9 months and are reasonably well-correlated with field-based progeny tests. Operating costs of the Center are shared by both the USDA Forest Service and its clients. The technologically sophisticated methods and professional skills of the Center staff have been applied to facilitate and accelerate progress in region-wide timber production, scientific understanding of the fusiform rust pathosystem, and graduate education of forest geneticists and pathologists in universities.}, number={3}, journal={FORESTS}, author={Cowling, Ellis and Young, Carol}, year={2013}, month={Sep}, pages={666–692} }

The Atlanta Supersite Project was located at the existing Southeastern Aerosol Research Characterization Study (SEARCH)/Aerosol Research Inhalation Epidemiology Study (ARIES) site on Jefferson Street in NW Atlanta, Georgia. The primary objective of the Atlanta Supersite Project was to evaluate and compare advanced measurement methods for particulate matter mass and its components. Methods included filter‐ and denuder‐based time‐integrated or discrete samplers, a variety of semicontinuous methods measuring mass, its major components (sulfate, nitrate, ammonium, organic carbon, elemental carbon, trace elements) and gas‐phase precursors, and for the first time ever, a comparison among particle mass spectrometers; four in total. These data were complemented by meteorological data as well as gas‐phase criteria pollutant measurements and other supplemental data such as particle physical properties, volatile organic compounds (VOC), oxygenated VOC, and NOy. The primary and supplemental data also were used to better understand the formation and accumulation of particulate matter in Atlanta and to better understand source‐receptor relationships. This paper overviews the study, summarizing objectives, the site and measurements, and the relative reference data used for comparisons, and it overviews the meteorological and chemical characteristics of pollution in Atlanta during the study, puts the study in context of Atlanta and the southeast United States, and finally summarizes the key findings from the over 30 publications published, submitted, or in preparation.

Circulation of anthropogenic Nr in Earth’s atmosphere, hydrosphere, and biosphere has a wide variety of consequences, which are magnified with time as Nr moves along its biogeochemical pathway. The same atom of Nr can cause multiple effects in the atmosphere, in terrestrial ecosystems, in freshwater and marine systems, and on human health. We call this sequence of effects the nitrogen cascade. As the cascade progresses, the origin of Nr becomes unimportant. Reactive nitrogen does not cascade at the same rate through all environmental systems; some systems have the ability to accumulate Nr, which leads to lag times in the continuation of the cascade. These lags slow the cascade and result in Nr accumulation in certain reservoirs, which in turn can enhance the effects of Nr on that environment. The only way to eliminate Nr accumulation and stop the cascade is to convert Nr back to nonreactive N2.}, number={4}, journal={BIOSCIENCE}, author={Galloway, JN and Aber, JD and Erisman, JW and Seitzinger, SP and Howarth, RW and Cowling, EB and Cosby, BJ}, year={2003}, month={Apr}, pages={341–356} }

Most of these studies were undertaken to provide new or refined knowledge about ozone accumulation and to assist in the development of economical and effective emissions management practices for ozone. In this paper, we describe a selection of field research programs conducted under a wide range of geographical and climatological conditions in North America and Europe. The designs of these studies were generally similar, employing a combination of ground-based observation networks, upper-air sampling, and meteorological observations. Analysis and interpretation of the resulting data were combined with improved inventories of ozone precursor emissions and air quality modeling to develop new or enhanced knowledge about photochemical processes under various tropospheric conditions. The scientific results from these studies contained few surprises; in fact, they generally affirmed the conclusions in the review by the US National Research Council (NRC, 1999). Key findings include: (1) reaffirmation that tropospheric ozone is a multi-scale phenomenon extending to continental boundaries; (2) aerometric conditions aloft are important to ground-level ozone; (3) biogenic sources make important contributions to VOC and NOx emissions in parts of eastern North America and southern Europe; (4) emissions estimates are among the more uncertain components of predictive models for ozone; (5) recirculating flow over complex terrain and large water bodies are universally important factors affecting accumulation of ozone at the ground; (6) nonlinearities in ozone response to precursor changes create important degrees of freedom in management strategies – VOC and NOx sensitivities vary extensively in urban and rural areas, making decisions about emissions management complicated; (7) measurement methods for many precursors, intermediates, and products of photochemical reactions have improved greatly; and (8) additional analysis and interpretation of existing data from many of these field studies should pay handsome dividends at relatively modest cost.}, number={12-14}, journal={ATMOSPHERIC ENVIRONMENT}, author={Solomon, P and Cowling, E and Hidy, G and Furiness, C}, year={2000}, pages={1885–1920} }

He became America's most skilled scientist in the theory and practice of forest pathology. He studied how long-lived forest trees, unlike most plants, cope with the long-term changes in their biological, physical, and chemical environments. He devoted his remarkably energetic life to learning, understanding, and teaching how trees survive disease stresses induced by biotic and abiotic agents—in forest nurseries, as individual trees, in young sapling stands, in naturally regenerated and planted stands, in old-growth forests, and in landscapes and watersheds. He focused his innovative spirit, curiosity, and high intelligence on seeking ways to use this un- derstanding to develop practical guidelines for management that can be used to decrease or minimize disease losses and deterioration of wood in service. From the research that he and his close co-workers completed have come many tangible benefits. Throughout his life, Hepting was devoted to maintaining the rich biolog- ical heritage of this country in its forests and wildlife resources, in national, state, and city parks, and trees in residential, commercial, and recreational landscapes— resources that are important, not only to the economic vitality, but also for the spirit and aesthetic quality of life in the United States.}, number={1999}, journal={Annual Review of Phytopathology}, author={Cowling, E.

Precipitation is an important process by which compounds are scavenged from the atmosphere and deposited onto the earth's surface. The purpose of this paper is to compare the emissions of nitrogen oxides (NOx) and sulfur dioxide (SO2) in each of the 48 continguous states in the USA with measured wet deposition of nitrate (NO3−) and sulfate (SO42−) in each state for the year 1990. With one exception (Vermont), wet deposition of N as nitrate was less than emissions of N as nitrogen oxides on a statewide basis in 1990. The median wet N deposition/emission value was 0.21. Wet plus dry N deposition of nitrate was estimated to represent 43% of NOx emissions in North Carolina. Wet deposition of S was less than emissions in 1990 in all but five states (Vermont, Maine, Arkansas, Nebraska, and South Dakota). The median value of wet deposition of sulfate/SO2 emissions was 0.34. In North Carolina, dry deposition of sulfate was estimated to represent an additional 21% of emissions, so that total deposition accounted for 60% of S emissions.

So far, the processes of enhancing agricultural and forest production and making pollution-control adjustments in the industrial, commercial, agricultural, and transportation systems of society have proceeded in more or less complete isolation from concern about the environmental consequences of human alterations in the nitrogen cycle of the earth. Also, most pollution abatement and mitigation strategies have so far been aimed at resolving one or another particular societal pollution problem in which oxidized and reduced forms of nitrogen play a part. The time has come to consider alternative, more fully integrated strategies and tactics by which to optimize societal efforts to maintain or increase agricultural and forest production while also enhancing the effectiveness and decreasing the cost of abating or mitigating various nitrogen-induced aspects of soil-, air-, and water pollution. In this paper we explore three general ideas: (1) some important similarities and differences in agriculture, forestry, and industry in the Netherlands and North Carolina and what they mean for nitrogen pollution management in our two home societies, (2) justification for adopting a “total fixed nitrogen approach” rather than continuing to deal with oxidized and reduced forms of nitrogen separately, and (3) developing a “concept of optimum nitrogen management for society”.}, journal={ENVIRONMENTAL POLLUTION}, author={Cowling, EB and Erisman, JW and Smeulders, SM and Holman, SC and Nicholson, BM}, year={1998}, pages={599–608} }

In the summers of 1994 and 1995, SOS implemented the Nashville/Middle Tennessee Ozone Study. This effort, the second SOS urban intensive study, conducted a series of integrated, process‐oriented airborne and surface measurement experiments to better understand the chemistry and meteorology associated with the production, transport, and impact of tropospheric ozone. Specific technical objectives addressed (1) the role of biogenic VOC and NO x emissions on local and regional ozone production, (2) the effect of urban‐rural exchange/interchange on local and regional ozone production, (3) sub‐grid‐scale photochemical and meteorological processes, and (4) the provision of a high‐quality chemical and meteorological data set to test and improve observation‐ and emission‐based air quality forecast models. Some of the more significant findings of the 1994–1995 studies include the following: (1) Ozone production in Nashville was found to be close to the transition between NO x ‐sensitive and VOC‐sensitive chemistry. (2) Ozone production efficiency (OPE) in power plant plumes, molecules of ozone formed per molecule of NO x emitted, was found to be inversely proportion to NO x emission rate, with the plants having the greatest NO x emissions exhibiting the lowest OPE. (3) During stagnant conditions, nighttime winds dominated pollutant transport and represent the major mechanism for transporting urban pollutants to rural areas. Ultimately, results provided by this research will allow improved assessment of existing ozone management strategies and provide better scientific tools for the development of future management strategies.}, number={D17}, journal={JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES}, author={Meagher, JF and Cowling, EB and Fehsenfeld, FC and Parkhurst, WJ}, year={1998}, month={Sep}, pages={22213–22223} }

An analysis of ozone data gathered in 1995 by the Southern Oxidants Study Spatial Ozone Network (SON) and EPA’s Clean Air Status and Trends Network (CASTNet) indicates that promulgation of this new standard will bring large parts of the rural eastern United States into nonattainment.
