Abstract. A field study was undertaken to investigate the accuracy of two micrometeorological flux footprint models when calculating the gas emission rate from a 10 × 10 m synthetic surface area source, based on the vertical flux of gas measured 15 to 50 m downwind of the source. Calculations were made with an easy-to-use tool based on the Kormann-Meixner analytical model and with a more sophisticated Lagrangian stochastic dispersion model. A total of 323 10 minute observation periods were measured over 9 days. On average, each of the two models calculated the emission rate to within 10 % of the actual release rate. No clear differences were observed between the two models in terms of overall accuracy.

现场测试两种通量足迹模型

摘要。基于在源下风向 15 至 50 m 处测得的气体垂直通量，进行了一项实地研究，以研究两种微气象通量足迹模型在计算 10 × 10 m 合成表面积源的气体排放率时的准确性。使用基于 Kormann-Meixner 分析模型和更复杂的拉格朗日随机色散模型的易于使用的工具进行计算。在 9 天内总共测量了 323 个 10 分钟的观察期。平均而言，两个模型中的每一个计算的排放率都在实际排放率的 10% 以内。就整体精度而言，两种模型之间没有观察到明显差异。
