The extraction of unconventional oil and natural gas from shale energy reservoirs has raised concerns regarding upstream and midstream activities and their potential impacts on air quality. Here we present in situ measurements of ambient methane concentrations near multiple natural gas compressor stations in New York and Pennsylvania using cavity ring-down laser spectrometry coupled with global positioning system technology. These data reveal discernible methane plumes located proximally to compressor stations, which exhibit high variability in their methane emissions depending on the weather conditions and on-site activities. During atmospheric temperature inversions, when near-ground mixing of the atmosphere is limited or does not occur, residents and properties located within 1 mile of a compressor station can be exposed to rogue methane from these point sources. These data provide important insight into the characterization and potential for optimization of natural gas compressor station operations.
从页岩能源藏中提取非常规石油和天然气引起了人们对上游和中游活动及其对空气质量潜在影响的关注。在这里，我们使用腔衰荡激光光谱法结合全球定位系统技术，对纽约州和宾夕法尼亚州多个天然气压缩机站附近的环境甲烷浓度进行了现场测量。这些数据揭示了在压缩机站附近可探测到甲烷羽流，其甲烷排放具有很大的可变性，取决于天气条件和现场活动。在大气逆温期间，当近地面大气混合受到限制或不存在时，位于压缩机站 1 英里范围内的居民和财产可能会接触到这些点源的甲烷。这些数据为天然气压缩机站运行的表征和优化提供了重要的见解。
