CMS: Atmospheric CO2 and C Isotopes, Fossil Fuel Contributions, California, 2014-2015

This dataset provides measurements of atmospheric CO2 concentrations, carbon isotopes d13C and D14C, and fossil fuel CO2 (ffCO2) estimates from nine observation sites in California over three month-long campaigns in separate seasons of 2014-2015. ffCO2 was quantified based on the CO2 concentration and D14C. Simulations of ffCO2 at the sites and times of the observations were conducted with the Vulcan v2.2 fossil fuel emissions estimate for 2002 and the Weather Research and Forecasting - Stochastic Time-Inverted Lagrangian Transport (WRF-STILT) atmospheric model. The observed and simulated ffCO2 were incorporated into Bayesian inverse estimates of ffCO2 to calculate California's ffCO2 emissions during the campaign period.

本数据集提供了2014-2015年间，加利福尼亚州九个观测站点在不同季节的三个月度长期观测中，大气二氧化碳浓度、碳同位素d13C和D14C的测量值，以及化石燃料二氧化碳（ffCO2）的估算数据。ffCO2的量化基于二氧化碳浓度和D14C值。利用Vulcan v2.2化石燃料排放估算模型（针对2002年）和天气研究预报——随机时间倒转拉格朗日传输（WRF-STILT）大气模型，对观测站点和时间的ffCO2进行了模拟。观测和模拟的ffCO2数据被纳入贝叶斯反演估算中，以计算加利福尼亚州在观测期间的ffCO2排放量。
