Reflection spectra repository

A database of >50,000 reflection spectra of cool giant exoplanets. The models explore the effect of temperature, gravity, metallicity, and sedimentation efficiency on the visible wavelength geometric albedo of cool giant planets. The animation below shows the prominence of water absorption signatures computed from this repository:
