Ultra-violet measurements from station Boulder, SURFRAD (2007-07)

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（UV-b values）最初以毫瓦每平方米（mW/m²）为单位给出，随后在导入时错误地直接沿用原数值，以瓦每平方米（W/m²）为单位录入。该数据集已于2017年2月9日完成修正，将所有数值除以1000。
