Ultra-violet measurements from station Sioux Falls (2007-04)

UV-b values were originally given in mW/m² and then erroneously imported in W/m² using the same numbers. The numbers have been corrected (divided by 1000) on 2017-02-03.

紫外线B波段（UV-b）的原始数值单位为毫瓦每平方米（mW/m²），后因操作失误，直接将原数值以瓦每平方米（W/m²）为单位导入数据集。该数据集的数值已于2017年2月3日完成修正，修正方式为将原数值除以1000。
