Solar radiation measurements (PAR) at ALOHA Station during cruise HOT-80

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.

辐射测量被限制在400至700纳米的波段范围内。该波段被定义为光合有效辐射（Photosynthetically Active Radiation, PAR），同时也是光合可用光的波段界限（Booth, 1976）。研究采用了2π收集器。
