Autor: Marco Zanatta, Heiko Bozem, Franziska Köllner, Johannes Schneider, Daniel Kunkel, Peter Hoor, Julia de Faria, Andreas Petzold, Ulrich Bundke, Katherine Hayden, Ralf M. Staebler, Hannes Schulz, Andreas B. Herber

Publikováno v: Tellus: Series B, Chemical and Physical Meteorology, Vol 72, Iss 1, Pp 1-24 (2020)

The influence of shipping on air quality over the Southern Baltic Sea was investigated by characterizing the horizontal and vertical distribution of aerosols and trace gases using airborne measurements in the summer of 2015. Generally, continental an

Measured Canadian oil sands CO2 emissions are higher than estimates made using internationally recommended methods

Autor: John Liggio, Shao-Meng Li, Ralf M. Staebler, Katherine Hayden, Andrea Darlington, Richard L. Mittermeier, Jason O’Brien, Robert McLaren, Mengistu Wolde, Doug Worthy, Felix Vogel

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-9 (2019)

Evaluating GHG emissions reported to inventories for the oil and gas (O&G) sector is important for countries with resource-based economies. Here the authors provide a top-down assessment of GHG emissions from the Canadian oil sands and find previous

Reconciling the total carbon budget for boreal forest wildfire emissions using airborne observations

Publikováno v: Atmospheric Chemistry and Physics. 22:12493-12523

Wildfire impacts on air quality and climate are expected to be exacerbated by climate change with the most pronounced impacts in the boreal biome. Despite the large geographic coverage, there is limited information on boreal forest wildfire emissions

Aerosol deposition to the boreal forest in the vicinity of the Alberta Oil Sands

Autor: Timothy Jiang, Mark Gordon, Paul A. Makar, Ralf M. Staebler, Michael Wheeler

Measurements of size-resolved aerosol concentration and fluxes were made in a forest in the Athabasca Oil Sands Region (AOSR) of Alberta, Canada, in August 2021 with the aim of investigating (a) particle size distributions from different sources, (b)

High sulphur dioxide deposition velocities measured with the flux/gradient technique in a boreal forest in the Alberta oil sands region

Autor: Mark Gordon, Dane Blanchard, Timothy Jiang, Paul A. Makar, Ralf M. Staebler, Julian Aherne, Cris Mihele, Xuanyi Zhang

The emission of SO2 from the Athabasca oil sands region (AOSR) has been shown to impact the surrounding forest area and human exposure. Recent studies using aircraft-based measurements have demonstrated that deposition of SO2 to the forest is at a ra

Validation of MAX-DOAS retrievals of aerosol extinction, SO2, and NO2 through comparison with lidar, sun photometer, active DOAS, and aircraft measurements in the Athabasca oil sands region

Publikováno v: Atmospheric Measurement Techniques. 13:1129-1155

Vertical profiles of aerosols, NO2, and SO2 were retrieved from Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) measurements at a field site in northern Alberta, Canada, during August and September 2013. The site is approximately 1

Fugitive Emissions of Volatile Organic Compounds from a Tailings Pond in the Oil Sands Region of Alberta

Autor: Amy Leithead, Yuan You, Stewart G. Cober, Shao-Meng Li, Meguel A. Yousif, Zhimei Jiang, John Liggio, James Beck, Andrea Darlington, Sumi N. Wren, Samar G. Moussa, P. C. Brickell, Jeffrey R. Brook, Ralf M. Staebler

Publikováno v: Environmental sciencetechnology. 55(19)

Tailings ponds in the oil sands (OS) region in Alberta, Canada, have been associated with fugitive emissions of volatile organic compounds (VOCs) and other pollutants to the atmosphere. However, the contribution of tailings ponds to the total fugitiv

Direct detection of atmospheric atomic bromine leading to mercury and ozone depletion

Autor: Daniel Obrist, Alexandra Steffen, Paul B. Shepson, Stephen M. McNamara, A. R. W. Raso, Christopher W. Moore, Ralf M. Staebler, Siyuan Wang, Kerri A. Pratt

Publikováno v: Proceedings of the National Academy of Sciences. 116:14479-14484

Bromine atoms play a central role in atmospheric reactive halogen chemistry, depleting ozone and elemental mercury, thereby enhancing deposition of toxic mercury, particularly in the Arctic near-surface troposphere. However, direct bromine atom measu
