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.
