Ultra-violet measurements from station Boulder, SURFRAD (2012-01)

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（紫外线B）数值最初以毫瓦每平方米（mW/m²）为单位给出，后续却错误地将相同数值以瓦每平方米（W/m²）为单位导入。该数据集的数值已于2017年2月9日完成修正，修正方式为将原数值除以1000。
