Solar radiation measurements (PAR) at ALOHA Station during cruise HOT-17

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.

辐射测量被限定在400至700纳米的波长范围内。此波长范围被定义为光合有效辐射（PAR），并作为光合作用有益光的波长界限（Booth, 1976）。实验中使用了2π收集器。
