The “ideal” spectrograph for atmospheric observations [PDF]

Atmospheric Measurement Techniques, 2021
Abstract. Spectroscopy of scattered sunlight in the near-UV to near-IR spectral ranges has proven to be an extremely useful tool for the analysis of atmospheric trace gas distributions. A central parameter for the achievable sensitivity and spatial resolution of spectroscopic instruments is the étendue (product of aperture angle and entrance area) of ...
