Solar radiation measurements (PAR) at ALOHA Station during cruise HOT-40

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.

辐射测量范围限定于400至700纳米（nm）的波段。
该波段被定义为光合有效辐射（Photosynthetically Active Radiation, PAR），同时也是光合有效光的波段范围（Booth, 1976）。
使用了2π收集器。
