Liu (Research Articles, 13 October 2017) inferred carbon flux anomalies in tropical continents with enough confidence to constrain the driving carbon-exchange processes. I show that they underestimated their error budget and that more effort must be invested in the satellite concentration retrievals and in the atmospheric transport models before such precision can be achieved.
刘（研究文章，2017 年 10 月 13 日）有足够的信心推断出热带大陆的碳通量异常，从而限制了碳交换过程的驱动力。我表明，他们低估了自己的误差预算，在实现如此精度之前，必须在卫星浓度反演和大气输送模型方面投入更多的努力。
