About this Dataset

In Situ Methane Mole Fraction Observations From Three Sites In The Washington DC Region From The NIST Northeast Corridor Project: January 2015 - December 2022

Methane (CH4) mole fraction data collected from three tower sites in the Washington DC area: Bucktown, MD (BUC, ghg01), Stafford, VA (SFD, ghg65), and Thurmont, MD (TMD, ghg61), as part of NIST's Northeast Corridor Urban Testbed project, presented as 1-minute averages. This data is published for research academic and related non-commercial purposes consistent with NIST?s mandate to further the science and the promulgation of appropriate standards. This dataset was used in the following publication and this archive represents the static archive of the data used in the publication and is not updated or modified: Sahu, S., Ahn, D., Loughner, C., and Dickerson, R., "Influence of synoptic weather patterns on methane mixing ratios in the Baltimore/Washington region", Atmospheric Environment, Volume 334, 2024, 120675, ISSN 1352-2310,https://doi.org/10.1016/j.atmosenv.2024.120675.Data is described further in the Readme document and references cited within.
