Ultra-violet measurements from station Boulder, SURFRAD (2009-12)

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 2017-02-09.UV-b值最初以毫瓦每平方米（mW/m²）为单位标注，后被错误地以相同数值导入为瓦每平方米（W/m²）单位。相关数值已于2017年2月9日完成修正（除以1000）。
