Ultra-violet measurements from station Boulder, SURFRAD (2006-09)

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 2017-02-09.UV-b值最初以mW/m²为单位给出，后续在数据导入环节因操作失误，以W/m²为单位导入数据时直接沿用了原数值，未进行单位换算。该数据集的相关数值已于2017年2月9日完成校正，校正方式为将原数值除以1000。
