Vertical Profile of Photosynthetic Active Radiation in McMurdo Dry Valley Lakes

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, lakes were monitored for photosynthetic active radiation (PAR) levels. This data set exemplifies the vertical profile of underwater PAR profiles in perennial ice covered lakes and ambient PAR measured at the air-ice interface. Profile data can be used to calculate extinction coefficients for the water column and ice layer.本数据集依托南极洲麦克默多干谷的长期生态研究（Long Term Ecological Research，LTER）项目，针对区域内湖泊的光合有效辐射（Photosynthetic Active Radiation，PAR）水平开展了监测工作。该数据集呈现了常年冰覆湖泊的水下PAR垂直剖面特征，以及冰-空气界面处的环境PAR实测数据。所提供的剖面数据可用于计算水体柱与冰层的消光系数。
