Chevallier showed a column CO ([Formula: see text]) anomaly of ±0.5 parts per million forced by a uniform net biosphere exchange (NBE) anomaly of 2.5 gigatonnes of carbon over the tropical continents within a year, so he claimed that the inferred NBE uncertainties should be larger than presented in Liu We show that a much concentrated NBE anomaly led to much larger [Formula: see text] perturbations.
谢瓦利埃展示了一个柱 CO([公式：见正文])异常值，其被一个均匀的净生物圈交换 (NBE) 异常值强迫，在一年内，热带大陆的 NBE 异常值为 25 亿吨碳，因此他声称推断的 NBE 不确定性应该比刘的报告中更大。我们表明，一个更集中的 NBE 异常导致了更大的[公式：见正文]扰动。
