I am using a Pandora spectrometer and a MAX-DOAS spectrometer to quantify the amount of formaldehyde (HCHO) present in the troposphere and stratosphere in Fairbanks, Alaska. Both the spectrometers use the Lambert-Beer's law for quantifying the amount of HCHO in the air by using different viewing geometries. I want to know what role does the view geometry play in the working of these spectrometers.

  • $\begingroup$ @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? $\endgroup$ – Semidiurnal Simon Jul 11 '18 at 12:32
  • $\begingroup$ 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. $\endgroup$ – Sujai Banerji Jul 11 '18 at 22:29
