May be a better fit for astronomy stack exchange?

@gimelist the question is about methods for measuring the composition of the earth's atmosphere. I guess Chemistry might be relevant, but why on earth astronomy?

I believe the Earth Sciences is an interdisciplinary science, and in fact the answer that I have written is mostly inspired by the input I got from Physics Stack Exchange.

What are the benefits of direct sun viewing spectrometer over a backscatter measuring spectrometer to quantify trace gases in the atmosphere?
