Did you consider supporting remissive and "emissive" measurements of e.g. a graycard to estimate ambient conditions in Argyll? I had some success using this method, whereas the handling is not exactly easy.
I have played that sort of game with a Spectrocam, but hadn't really though of using that approach for ambient measurements. Of course it's better with a reflection measuring instrument, since the ambient collection surface can be measured. Graeme Gill.
