I'm not at all clear on what labels the various stations use. I would use "solar irradiance" or less pedantically "solar radiation". The term "field radiation" is interesting and I have not previously encountered it. For the arriving light per unit area, the term is Illuminance. Luminosity strictly refers to total power departing a light source. https://en.wikipedia.org/wiki/Solar_irradiance https://en.wikipedia.org/wiki/Illuminance One cannot accurately convert illuminance to irradiance, because illuminance applies wavelength-based weights to power based on human visual response. So, two light sources arriiving at a surface, having the same illuminance, will in general have differenrt irradiances. But people assume "sunlight" and then onc can make a reasonable approximation. My previous rant: https://github.com/weewx/weewx/wiki/Watts-and-lux and something I just found that seems interesting https://ieee-dataport.org/open-access/conversion-guide-solar-irradiance-and-lux-illuminance > It's not the place for the GW1000 driver to derive obs such as > radiation from other obs, rather derived observations should be > derived by the StdWXCalculate service.
