During its first Earth flyby, the JUpiter Icy Moons Explorer (Juice) spacecraft acquired observations over the Western Pacific. We identify several gaseous compounds (O₂, H₂O, CO₂, O₃, CH₄, N₂O), liquid/ice clouds over the ocean and atmospheric waves at high altitudes. We find good agreement with similar observations of Earth-orbiting PRISMA spectrometer. This study helps in planning future observations from the Moon and Jupiter Imaging Spectrometer (Majis) when it comes to the Jupiter system.
