Nominal HWO resolutions suffice to detect key biosignatures across Archean to Phanerozoic Earth atmospheres, with O3 enabling indirect low-O2 detection and NIR resolution preventing CO2-CO false positives.
LIFE can constrain atmospheric H2O abundances from roughly 10^{-3} to 1 bar surface pressure on Earth-like exoplanets for certain vertical profiles, providing a potential proxy for surface oceans, but cannot detect water below 10^{-6} bar or precisely characterize the highest abundances.

The Goldilocks problem for detecting water in terrestrial planets: Constraining water abundances in the mid-IR with LIFE
