Scope
GB/T 33872-2017 is the English-translated version of 太阳能资源观测站分类指南.
GB/T 33872-2017 is the Chinese national guide for classifying the stations that observe solar energy resources. It gives the classes of station, the elements each class observes, guidance on the instruments used for them and the requirements the site of such a station has to meet.
It takes its terms from GB/T 31163-2014 and repeats the ones it needs: the solar energy resource that can be turned into heat, electricity or chemical energy for human use, diffuse radiation, direct radiation, ultraviolet radiation and photosynthetically active radiation.
Ultraviolet radiation is placed between 100 nm and 400 nm and split into the UV-A, UV-B and UV-C bands, while photosynthetically active radiation is the band generally taken as 400 nm to 700 nm. It was issued on 12 July 2017 and has applied since 1 February 2018.

GB/T 31163-2014 Terminology of solar energy resources
3 Terms and definitions
The following definitions and definitions as defined in GB/T 31163-2014 apply to this document.
3.1 Solar resources
Can be converted into heat, electricity, chemical energy for human use of solar energy. [GB/T 31163-2014, definition 2.2]
3.2 Scattered radiation
Solar radiation is dispersed by air molecules, clouds and air particles into non-directional, but does not change its monochromatic composition of radiation. [GB/T 31163-2014, definition 5.14]
3.3 Direct radiation
From the surface and its surrounding a small solid angle emitted within the radiation. [GB/T 31163-2014, definition 5.11]
3.4 Ultraviolet radiation
Wavelengths less than visible radiation and greater than the radiation of electromagnetic radiation.
Note: UV radiation between 100nm and 400nm can be subdivided into three bands. UV-A (315nm ~ 400nm), UV-B (280nm ~ 315 nm), UV-C (100 nm to 280 nm). [GB/T 31163-2014, definition 5.5]
3.5 Photosynthetically active radiation
The solar radiation spectrum can be absorbed, transformed and used to synthesize the radiant energy of a certain band of organic matter by the green plant's plastid pigment.
Note: generally 400nm ~ 700nm solar radiation known as photosynthetically active radiation. [GB/T 31163-2014, definition 5.8]
