Global Radiation

[carstenhoyerklick]

Description of the issue

We want to define the global solar radiation. This is is derived from #1031, #1067 and #1072

Ideas of solution

This will be a subcasss of solar radiation (....ocurrent -> process -> radaition -> solar radiation)

Suggested definition: Global Radiation is solar radiation received on a surface from a solid angle of 2pi steradians. It consists of direct radiation and diffuse radiation.

Adapted from WMO G0560.

Workflow checklist

• [x ] I discussed the issue with someone else than me before working on a solution
• [ x] I already read the latest version of the workflow for this repository
• [ x] The goal of this ontology is clear to me

I am aware that

• [ x] every entry in the ontology should have a definition
• [ x] classes should arise from concepts rather than from words

To me, this reads more like some kind of quantity value than a process.

As it is the combination of direct and diffuse radiation, it should be in the same place below solar radaition. These three define the main "components" of solar radiation.
