Ultra-violet measurements from station Sioux Falls (2012-05)

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）数值最初以毫瓦每平方米（mW/m²）为单位给出，后因录入失误以相同数值按瓦每平方米（W/m²）进行导入。相关数值已于2017年2月3日完成修正（除以1000）。
