In their study, Dong and Ochsner (2018, https://doi.org/10.1002/2017WR021692) used an extensive data set of 18 cosmic‐ray neutron rover surveys along a 150 km long transect on unpaved roads to assess the influence of precipitation and soil texture on mesoscale soil moisture patterns. Based on their analysis, they concluded that soil texture, represented by sand content, exerted a stronger influence on mesoscale soil moisture variability than precipitation, represented by the antecedent precipitation index, on 17 of the 18 survey days. However, we found that Dong and Ochsner (2018) made a mistake in their calculation of volumetric soil moisture. After correction, the validity of the original conclusions of Dong and Ochsner (2018) was considerably weakened, as soil texture exerted a stronger influence on soil moisture than precipitation on 12 of the 18 survey days only.

对Dong和Ochsner（2018）的评论：“土壤质地通常比降水对中尺度土壤水分模式的影响更大”

在他们的研究中，Dong和Ochsner（2018，https://doi.org/10.1002/2017WR021692）在未铺设的道路上沿150公里长的横断面使用了18个宇宙射线中子流浪者调查的广泛数据集，以评估降水的影响和土壤质地对中尺度土壤水分模式的影响。根据他们的分析，他们得出结论，在18个调查日中的17天中，以沙子含量为代表的土壤质地对中尺度土壤水分变异性的影响要比以前降水指数代表的降水对降水的影响更大。但是，我们发现Dong和Ochsner（2018）在计算土壤体积含水量时犯了一个错误。经过更正后，Dong和Ochsner（2018）的原始结论的有效性被大大削弱了，
