准确测量CO2在大气中的垂直分布对于验证卫星和地基光谱仪及估计CO2源、汇至关重要.本文描述了一种原位大气采样系统(aircore).我们利用这套系统在内蒙古锡林浩特地区于2018年6月13日和14日获取了CO2和CO廓线并与对流层监测仪(TROPOMI),轨道碳观测(OCO-2)和哥白尼大气监测服务(CAMS)比较.TROPOMI监测的CO柱总浓度(XCO)与原位测量CO廓线计算的XCO一致,平均偏差为5±1.89 ppb.OCO-2监测的CO2柱总浓度与原位测量廓线所得结果一致,平均偏差为.0.4±0.6ppm.6月13日,OCO-2后验廓线与原位测量廓线有明显偏差,OCO-2低估了250 hPa和600 hPa高度间的CO2浓度,高估了600 hPa高度以下的CO2浓度.CAMS的CO...
