Site selection and effects of background towers on urban CO2 estimates: A case study from central downtown Zhengzhou in China

October 16, 2024
Author(s)
Ge Ren, Kailun Du, Shiqi Zhao, Anna Karion, Israel Lopez Coto, Xiaoning Wang, James Whetstone, Hong Lin
With China's proposed carbon reduction goals, many carbon monitoring pilot city projects have been launched, involving greenhouse gas (GHG) estimation inversion analysis based on GHG observations. For the evaluation of emissions estimates in a targeted

Underestimation of Thermogenic Methane Emissions in New York City (New York City methane emissions: what are we missing?)

May 14, 2024
Author(s)
Joseph R. Pitt, Israel Lopez Coto, Anna Karion, Kristian D. Hajny, Jay M. Tomlin, Robert Kaeser, Thilina Jayarathne, Brian H. Stirm, Cody R. Floerchinger, Christopher P. Loughner, Roisin Commane, Conor K. Gately, Lucy R. Hutyra, Kevin R. Gurney, Geoffrey S. Roest, Jianming Liang, Sharon Gourdji, Kimberly Mueller, James Whetstone, Paul B. Shepson
Recent studies have shown that methane emissions are underestimated by inventories in many US urban areas. This has important implications for climate change mitigation policy at the city, state, and national levels. Uncertainty in both the spatial

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

March 27, 2024

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

Analyzing "grey zone" Turbulent Kinetic Energy predictions in the Boundary Layer from three WRF PBL Schemes over New York City and comparison to Aircraft measurements

January 1, 2024

Austin Hope, Israel Lopez Coto, Kristian Hajny, Jay M Tomlin, Robert Kaeser, Brian Stirm, Anna Karion, James Whetstone, Paul Shepson
We conduct WRF simulations at multiple resolutions down to the "grey zone" (9 km, 3 km, 1 km, 333 m) to examine boundary layer turbulence in three planetary boundary layer (PBL) schemes: the well-established MYNN PBL scheme and the two newest PBL schemes

Spatial attribution of aircraft mass balance experiment CO2 estimations for policy relevant boundaries: New York City

November 17, 2023
Author(s)
Jay M. Tomlin, Israel Lopez Coto, Kristian D. Hajny, Joseph R. Pitt, Robert Kaeser, Brian H. Stirm, Thilina Jayarathne, Cody R. Floerchinger, Roisin Commane, Paul B. Shepson
To effectively address the unprecedented acceleration of climate change, cities across the U.S. are leading efforts to reduce greenhouse gas emissions. Coherent, aggressive, and lasting mitigation policies in controlling carbon emissions are beginning to

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

November 9, 2023
Author(s)
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

The impact of COVID-19 on CO2 emissions in the Los Angeles and Washington DC/Baltimore metropolitan areas

June 7, 2021
Author(s)
Kimberly Mueller, Anna Karion, Sharon Gourdji, Israel Lopez Coto, James Whetstone, Vineet Yadav, Geoffrey Roest, Kevin R. Gurney, Kristal R. Verhulst, Jooil Kim, Michael Stock, Elizabeth DiGangi, Steve Prinzivalli, Ralph Keeling, R. F. Weiss, Charles E. Miller, Clayton Fain, Riley Duren, Subhomoy Ghosh
Responses to COVID-19 has resulted in and unintended reductions of city-scale carbon dioxide (CO2) emissions. Here we detect and estimate decreases in CO2 emissions in Los Angeles and Washington DC/Baltimore during March and April 2020. Our analysis uses

Fluxes of Atmospheric Greenhouse-Gases in Maryland (FLAGG-MD): Emissions of Carbon Dioxide in the Baltimore-Washington, DC area

April 15, 2020
