Limits on the atmospheric metallicity and aerosols of the sub-Neptune GJ 3090 b from high-resolution CRIRES+ spectroscopy The sub-Neptune planets have no solar system analogues, and their low bulk densities suggest thick atmospheres containing degenerate quantities of volatiles and H/He, surrounding cores of unknown size...

You can read more about how high resolution spectroscopy can constrain sub-Neptune atmospheres (and provide constraints that are comparable with JWST…) in the paper we published this year! (ui.adsabs.harvard.edu/abs/2025MNRA...)
