CMS: Atmospheric Methane Concentrations and Prior Emissions, Boston, MA, 2012-2014

This data set provides average hourly measured, modeled enhancements, and background methane (CH4) concentrations, atmospheric ethane (C2H6) measurements, prior CH4 flux fields by sector, and a spatial reconstruction of natural gas (NG) consumption in Boston, Massachusetts and the surrounding region. Atmospheric CH4 concentrations were measured continuously from September 2012 through August 2013 at four locations and atmospheric ethane was measured continuously for several months during 2012-2014 at one location. Spatial models of prior CH4 emissions and natural gas consumption are given for an ~18,000 km^2 area centered on Boston, MA.

本数据集提供了平均每小时测量的、模型预测的增强值以及背景甲烷（CH4）浓度、大气乙烷（C2H6）的测量数据、先前各行业CH4通量场以及马萨诸塞州波士顿及其周边地区天然气（NG）消耗的空间重构。大气CH4浓度自2012年9月至2013年8月连续测量于四个地点，大气乙烷在2012年至2014年间于一个地点连续测量数月。针对以马萨诸塞州波士顿市为中心的约18,000平方公里区域，提供了先前CH4排放和天然气消耗的空间模型数据。
