Opacity-driven bottlenecks in decoding exoplanetary spectra

The limits of our knowledge on light–matter interactions (that is, opacity models) will affect the exploration of exoplanetary atmospheres. Accounting for these limits will prevent biased claims. Guided improvements in opacity models, their standardization and dissemination will ensure maximum return on investment from the next-generation observatories, including the JWST.
