Equatorial Mixing Ratios and their Variation over the Solar Cycle

Equatorial Mixing Ratios for Venus, Earth, and Mars vs. Height

Venus
VTGCM equatorial fields and their variations over the solar cycle. Noon (LT = 12, solid), and midnight (LT = 24, dashed) O/CO2 profiles over 100 to 180 km for SMIN, SMED, and SMAX cases.

Earth:
TIEGCM equatorial fields and their variations over the solar cycle. Midafternoon (LT = 16, solid), and early morning (LT = 4, dashed) O/O2+N2 profiles over 100 to 500 km for SMIN, and SMAX cases.

Mars:
MTGCM equatorial fields and their variations over the solar cycle. Midafternoon (LT = 15, solid), and early morning (LT = 4, dashed) O/CO2 profiles over 100 to 220 km for SMIN, SMED, and SMAX cases.
