Ultra-violet measurements from station Sioux Falls (2011-04)

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.UV-b值最初的单位为毫瓦每平方米（mW/m²），随后却错误地以瓦每平方米（W/m²）单位导入了完全相同的数值。该数据集的相关数值已于2017年2月3日完成修正（除以1000）。
