ActiveMeasurement for photosynthetic active radiation—Hemispherical radiometer method
光合有效辐射测量 半球向辐射表法
Application Summary AI generated
This standard specifies the measurement method for photosynthetic active radiation (PAR) using a hemispherical radiometer. It is applied in agricultural meteorology, ecology, and plant physiology research to quantify the solar radiation spectrum (400-700 nm) that drives photosynthesis. The standard is used for field calibration, environmental monitoring, and ensuring consistency in PAR data collection across crop growth studies and climate observation networks.
