UV radiation at Davis station summer 1998

Data provides the date, time and 10 min cumulative erythemal irradiance at Davis Station for downwelling solar radiation and the irradiance at depth beneath neutral density screen (ND-polythene) and 3.3, 5.5, and 9.0 mm borosilicate glass. These light treatments simulated watercolumn depths of 1.0, 2.0, 3.0, and 3.6 m depth (calculated using Beer's Law and the average UV transmittance of Antarctic seawater at 4 ice-edge sites). A no erythemal UV control (transmittance greater than 375 nm) was also used in which samples were incubated beneath UV-stabilised polycarbonate. The fields in this dataset are: date Davis solar time downwell wnd w3.3 w5.5 w9

本数据集收录了南极戴维斯站（Davis Station）的辐射观测数据，具体包括下行太阳辐射（downwelling solar radiation）的日期、时间与10分钟累积红斑辐照度（erythemal irradiance），同时涵盖中性密度聚乙烯滤光片（ND-polythene）下方以及3.3、5.5、9.0毫米硼硅酸盐玻璃下方的辐照度数据。上述光照处理方案分别模拟了1.0、2.0、3.0、3.6米的水柱深度，该模拟通过比尔定律（Beer's Law）结合南极海水在4个冰缘站点的平均紫外线透射率（UV transmittance）计算得出。本数据集还设置了无红斑紫外线对照组（no erythemal UV control），该组样本在经紫外线稳定处理的聚碳酸酯（UV-stabilised polycarbonate）下方进行孵育。本数据集包含以下字段：日期（date）、戴维斯太阳时（Davis solar time）、下行辐照度（downwell）、wnd、w3.3、w5.5、w9
