Photosynthetically active radiation below water surface (DP1.20261.001)

Photosynthetically active radiation below water is measured at 1 Hz at lake inlet and outlet sensor sets and twice per minute on buoys at lake and river sites. It is reported as 1-minute mean measurements and 30-minute mean values.

Latency:
Data collected in any given month are published during the second full week of the following month.

水下光合有效辐射（Photosynthetically Active Radiation，PAR）的采集方案如下：湖泊入水口与出水口的传感器组以1赫兹的频率采样，湖泊及河道监测站点的浮标则以每分钟两次的频率开展数据采集。最终发布的数据包含1分钟平均测量值与30分钟平均数值。
数据延迟说明：
当月采集的全部数据将于次月的第二个完整自然周内发布。
