Airborne measurements within the urban mixing layer (360 m) over Greater London are used to quantify CO(2) emissions at the meso-scale. Daytime CO(2) fluxes, calculated by the Integrative Mass Boundary Layer (IMBL) method, ranged from 46 to 104 μmol CO(2) m(-2) s(-1) for four days in October 2011. The day-to-day variability of IMBL fluxes is at the same order of magnitude as for surface eddy-covariance fluxes observed in central London. Compared to fluxes derived from emissions inventory, the IMBL method gives both lower (by 37%) and higher (by 19%) estimates. The sources of uncertainty of applying the IMBL method in urban areas are discussed and guidance for future studies is given.
在大伦敦的城市混合层（360 米）内进行的空气传播测量用于在中尺度上量化 CO(2)排放。2011 年 10 月四天内，通过综合质量边界层（IMBL）方法计算出的日间 CO(2)通量范围为 46 至 104 μmol CO(2) m(-2) s(-1)。IMBL 通量的日变化与在伦敦市中心观测到的地表涡度协方差通量相同数量级。与排放清单得出的通量相比，IMBL 方法给出的通量既低（低 37%）又高（高 19%）。讨论了在城市地区应用 IMBL 方法的不确定性来源，并为未来的研究提供了指导。
