沈阳地区大气CO2浓度的区域输送影响与排放源解析
Regional Transport Influence and Emission Source Analysis of Atmospheric CO2 Concentration in Shenyang Region
摘要
Abstract
Based on high-precision online atmospheric CO2 concentration measurements from the Shenyang Urban Ecological Station from June 2023 to May 2024,the REBS(robust extraction of baseline signal)al-gorithm is employed to separate regional background and pollution data.The influence of regional trans-port on atmospheric CO2 concentrations in Shenyang is analyzed using surface wind field data and MeteoInfo statistical software.The contributions of fossil fuel combustion emissions and ecosystem emissions/ab-sorption to CO2 concentration are estimated according to carbon conservation principles.The results show that the average CO2 concentration at Shenyang Urban Ecological Station is 477.2 × 10-6,with background and pollution concentrations averaged to be 474.9× 10-6 and 519.4× 10-6,respectively.High-concentration CO2 air masses affecting Shenyang originate from the southwest in spring and summer,and from north-west and southwest in winter.The potential CO2 emission source regions throughout the year are mainly distributed in most parts of Liaoning and Jilin provinces,southern Heilongjiang,eastern Inner Mongolia,Beijing-Tianjin-Hebei Region,Shandong Peninsula,and the Yellow Sea and Bohai Sea areas.Compared to fossil fuel combustion emission in other seasons,the fossil fuel combustion emission contri-butes more sig-nificantly to the atmospheric CO2 concentration in Shenyang during autumn and winter.关键词
