Ultra-violet measurements from station Sioux Falls (2009-09)

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（UV-b）值最初以毫瓦每平方米（mW/m²）为单位给出，后续录入过程中误将单位替换为瓦每平方米（W/m²）且未同步调整数值。该数据集已于2017年2月3日完成修正，修正操作为将所有数值除以1000。
