Solar radiation measurements (PAR) at ALOHA Station during cruise HOT-14

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纳米的波段范围内。该波段定义为光合有效辐射（PAR），并作为光合作用中具有利用价值的光线的波段极限（Booth, 1976）。本研究采用了双π型收集器。
