Dataset: Statistical evaluation of methane isotopic signatures determined during near-source measurements

Methane isotopic signature data collected during cotrolled release experiment. Cotrolled took place in September 2019 in Bedford and was a collaboration between NPL, RHUL and LSCE. Bag samples were collected during releases and measured aftterwards or using IRMs or CRDS. CRDS AirCore sampling was made in situ during methane release. Data were used to verify methods used to determien methane isotopic signature from mobile indorect measurements.本数据集为受控释放实验中采集的甲烷同位素特征数据。该实验于2019年9月在贝德福德（Bedford）开展，由英国国家物理实验室（NPL）、伦敦皇家霍洛威大学（RHUL）以及法国气候与环境科学实验室（LSCE）合作完成。实验释放期间采集了气袋样本，后续通过同位素比值质谱仪（IRMs）或腔衰荡光谱仪（CRDS）完成检测；甲烷释放过程中还开展了原位CRDS AirCore采样工作。本数据集用于验证基于移动间接测量获取甲烷同位素特征的相关方法。
