摘　　要：应用烟羽分割、背景插值和高斯烟羽模型,使用轨道碳监测传感器(OCO-3)SAM模式在1年内的4次有效观测数据,估算了托克托电厂CO_(2)排放量,并利用年度核算报告结果、月度发电量与连续排放监测系统(CEMS)监测数据对卫星遥感估算结果进行验证.结果表明,2021年4次卫星过境时CO_(2)排放速率分别为1900.82、3353.96、2941.07和3701.71tCO_(2)/h,其不确定性分别为25.10%、20.27%、19.59%和29.52%,不确定性主要来源于气象数据、背景和其它排放源影响.CO_(2)小时排放速率卫星遥感反演结果和核算分配结果验证具有较好的一致性,相关系数R为0.822.电厂月度发电量及小时级在线监测数据分析结果表明,电厂活动水平具有明显的季节性变化和小时变化特征,其中与CO_(2)排放密切相关的月度发电量相对标准偏差可达14.55%,NOx小时排放量相对标准偏差可达12.35%.This study had estimated CO_(2) emissions from the Tuoketuo Power Plant using observations from the Orbital Carbon Monitoring Satellite(OCO-3)SAM mode with segmentation,background-interpolation and Gaussian plume model.To verify the estimation results from satellite remote sensing,annual accounting report CO_(2) data,monthly power generation,and continuous emission monitoring system(CEMS)data were used.The results showed that the hourly CO_(2) emission rates of the four estimated results were 1900.82,3353.96,2941.07,and 3701.71tCO_(2)/h,respectively,with uncertainties of 25.10%,20.27%,19.59%,and 29.52%,and the uncertainty mainly came from meteorological data,background,and secondary sources.The satellite remote sensing inversion results of hourly CO_(2) emission rate were very consistent with the accounting allocation value,with a correlation coefficient of 0.822.The activity data of power plants showed an obvious seasonal and hourly variations,with a relative standard deviation of 14.55%for monthly power generation and 12.35%for NOx hourly emissions.
