Solar radiation measurements (PAR) at ALOHA Station during cruise HOT-5

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.

辐射测量被限定于400至700纳米的波段范围内。此波段定义为光合有效辐射（PAR），它是光合作用有益光线的波段极限（Booth, 1976）。在此过程中，采用了2π收集器。
