Solar radiation measurements (PAR) at ALOHA Station during cruise HOT-98

The measurements of radiation are restricted to the 400 to 700 nm waveband. This waveband is defined as Photosynthetically Active Radiation (PAR) and is the waveband limits for photosynthetically useful light (Booth, 1976). A 2-pi collector was used.

本次辐射测量的波段范围限定为400至700纳米（nm）。该波段被定义为光合有效辐射（Photosynthetically Active Radiation, PAR），亦是具备光合效用的光的波段范围边界（Booth，1976）。实验采用了2π型辐射收集器。
