Workshop on Quantifying Methane Emissions Across Natural Gas Infrastructure in Urban Environments

March 27, 2024
Author(s)
Anna Karion, Paul Shepson, Thomas Butcher, Roisin Commane, Julianne M Fernandez, Tom Ferrara, Kristian Hajny, Robert Jackson, Brian Lamb, Israel Lopez Coto, Zeyneb Magavi, Brian McDonald, Zachary Merrin, Scot Miller, Kimberly Mueller, Lee Murray, Joseph Pitt, Rick Trieste, Rebecca Trojanowski, Joseph von Fischer
A workshop was held at the EDF offices in Washington, DC, on June 15 and 16, 2022, to discuss the current state of knowledge and to define productive courses of action in better determination and source apportionment of methane emission rates, and

Methane emissions show recent decline but strong seasonality in two US Northeastern cities

November 9, 2023

Anna Karion, Subhomoy Ghosh, Israel Lopez Coto, Kimberly Mueller, Sharon Gourdji, Joseph Pitt, James Whetstone
Urban methane emissions have been found to exceed estimates derived using traditional inventory methods in several US cities. In large northeastern US cities, including in Washington, DC and Baltimore, Maryland, studies using atmospheric methane

IG3IS Urban Greenhouse Gas Emission Observation and Monitoring Best Research Practices

August 1, 2022
Author(s)
Jocelyn Turnbull, Philip DeCola, Kimberly Mueller, Felix Vogel, Anna Karion, Israel Lopez Coto, James Whetstone
The Integrated Global Greenhouse Gas Information System (IG3IS) aims to coordinate an integrated global greenhouse gas information system, linking inventory and process model-based information with atmospheric observations and atmospheric modelling, to

Background conditions for an urban greenhouse gas network in the Washington, D.C. and Baltimore metropolitan region

August 25, 2021
Author(s)
Anna Karion, Israel Lopez Coto, Sharon Gourdji, Kimberly Mueller, Subhomoy Ghosh, William Callahan, Michael Stock, Elizabeth DiGangi, Steve Prinzivalli, James Whetstone
As city governments take steps towards establishing emissions reduction targets, the atmospheric research community is increasingly able to assist in tracking emissions reductions. Researchers have established systems for observing atmospheric greenhouse

Siting background towers to characterize incoming air for urban GHG estimation: a case study in the Washington DC/Baltimore Area

June 5, 2019
Author(s)
Kimberly L. Mueller, Vineet Yadav, Israel Lopez Coto, Anna Karion, Sharon M. Gourdji, Cory R. Martin, James R. Whetstone
There is increased interest in understanding urban greenhouse gas (GHG) emissions. However, to accurately estimate city emissions, the influence of exurban fluxes must first be removed from urban greenhouse gas (GHG) observations. This is especially true

Inter-comparison of Atmospheric Trace Gas Dispersion Models: Barnett Shale Case Study

February 28, 2019
Author(s)
Anna Karion, Thomas Lauvaux, Israel Lopez Coto, Colm Sweeney, Kimberly L. Mueller, Sharon M. Gourdji, Wayne Angevine, Zachary R. Barkley, Aijun Deng, Ariel Stein, James R. Whetstone
Greenhouse gas emissions mitigation requires understanding dominant processes controlling fluxes of these trace gases into the atmosphere at increasingly finer spatial and temporal scales. Trace gas fluxes can be estimated using a variety of approaches

Evaluation of WRF-Chem Simulated Carbon Dioxide Atmospheric Transport and Emissions in the Baltimore / Washington Metropolitan Area

November 10, 2018
Author(s)
Cory R. Martin, Ning Zeng, Anna Karion, Kimberly L. Mueller, Subhomoy Ghosh, Israel Lopez Coto, Kevin Gurney, Tomohiro Oda, Kuldeep R. Prasad, Yun Liu, Russell R. Dickerson, James R. Whetstone
Urban areas are major sources of carbon dioxide (CO2) emissions, contributing to the increase in global concentrations and leading to concerns about Earth's future climate. In recent years, several urban testbeds have been implemented to improve and

Reducing the impact of transport model error in urban greenhouse gas inversion models using the Aliso Canyon natural gas leak as a natural tracer experiment

March 22, 2018
Author(s)
Sharon M. Gourdji, Vineet Yadav, Anna Karion, Kimberly L. Mueller, T. Conley, Stephen Conley, Tom Ryerson, Thomas Nehrkorn, Eric Kort
Urban greenhouse gas (GHG) flux estimation with atmospheric measurements and modeling, i.e., the “top-down” approach, can potentially support emission reduction policies by providing continuous data streams for trend and anomaly detection in conjunction
