[1]在论文“Sulfuric acid deposition from stratospheric geoengineering with sulfate aerosols”（Journal of Geophysical Research，114，D14109，doi：10.1029/2009 JD 011918，2009）中，有两个错误我们想纠正。第一个是算术错误。与我们计算的全球平均地表硫排放量5.41 × 10 kgSma相比，正确值为2.67 × 10 kgSma。这个值是作为参考值计算的，所以这个修正实际上加强了我们的结论，即地球工程产生的硫的额外量将比目前的来源小得多。[2]第二个错误涉及我们对一个公式的错误应用。在第4节中，我们将硫酸盐沉积的模型输出（单位为kg SO 4 m −2 a）转换为临界负荷研究中使用的形式（mEq m a）。我们的公式是这样的
[1] In the paper “Sulfuric acid deposition from stratospheric geoengineering with sulfate aerosols” (Journal of Geophysical Research, 114, D14109, doi:10.1029/2009JD011918, 2009), there are two errors that wewould like to correct. The first is an arithmetic error. In contrast to our calculation of the average global surface sulfur emissions of 5.41 × 10 kg Sm a, the correct value is 2.67 × 10 kg S m a. This value was calculated as a reference value, so this correction actually strengthens our conclusions that the additional amount of sulfur from geoengineering would be much smaller than current sources. [2] The second error involves our incorrect application of a formula. In section 4, we convert model output of sulfate deposition, given in kg SO4 m −2 a, to a form used in critical loading studies, mEq m a. Our formula as printed reads
