Solar radiation at Earth's surface is typically defined as total radiation across a wavelength rage of 280 to 4000 nm (shortwave radiation). Total solar radiation, direct beam and diffuse, incident on a horizontal surface is defined as global shortwave radiation, or shortwave irradiance (incident radiant flux), and is expressed in Watts per square meter (W m-2, equal to Joules per second per square meter).
Pytanometers是测量全球短波辐射的传感器。Apogee SP-500 and SP-600 series pyranometers are blackbody thermopile pyranometers, and are sensitive to most of the solar spectrum, thus eliminating spectral errors associated with silicon-cell pyranometers. The SP-510 is designed to measure incoming shortwave radiation and combines a diffuser with the blackbody detector. The SP-610 is designed to measure reflected shortwave radiation from terrestrial surfaces and combines a quartz windows with the blackbody detector. Both models have calibrations traceable to secondary standard blackbody thermopile pyranometers traceable to the world radiation reference in Davos, Switzerland. Specifications for both models meet the International Organization of Standardization (ISO) 9060:2018 Class C requirements.

地球表面的太阳辐射通常被定义为跨波长范围为280至4000nm(短波辐射)的总辐射。入射在水平表面上的总太阳辐射,直接梁和漫射被定义为全局短波辐射,或短波辐照度(入射辐射通量),并以瓦特每平方米表示(W M)-2)。
Pytanometers是测量全球短波辐射的传感器。bob体育竞技Apogee仪器提供硅细胞和黑体热电偶联器。硅 - 细胞粘嘴计仅对太阳光谱的一部分敏感,大约360至1100nm(大约80%的总短波辐射在该范围内)。
Typical applications of silicon-cell pyranometers include:
• Agricultural weather networks
• Ecological weather networks
• Hydrological weather networks
