Methane emissions estimates and related data sets for Washington DC and Baltimore, MD urban areas

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
