Description
This dataset accompanies the publication below. Here we provide the results of the analysis, including gridded estimates of methane emissions for the Washington/Baltimore area at 0.01 degrees resolution and monthly from 2017 through 2021. All files available for unrestricted public use with citation of this data set except the Observations_XX files. Observations are for non-commercial use only, as they are purchased from a private data provider (AEM, Inc. via Earth Networks, Inc.).Methane Emissions Show Recent Decline but Strong Seasonality in Two US Northeastern CitiesAnna Karion, Subhomoy Ghosh, Israel Lopez-Coto, Kimberly Mueller, Sharon Gourdji, Joseph Pitt, and James WhetstoneEnvironmental Science & Technology 2023 57 (48), 19565-19574 DOI: 10.1021/acs.est.3c05050
