Solar radiation measurements (PAR) at ALOHA Station during cruise HOT-91

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纳米的波长区间。此波长区间被定义为光合有效辐射（PAR），并作为光合作用有益光线的波长极限（Booth, 1976）。本研究采用了2π收集器。
