H2 Chemistry and Protonation in the Dayside Venusian Upper Atmosphere

Although H _2 is present in low concentrations, it critically controls the structure and composition of planetary upper atmospheres through protonation under solar extreme-ultraviolet and soft X-ray irradiation. Recent studies highlight the importance of protonation on Venus. As H _2 concentrations...
