Solar Maximum Conditions at Equinox

Neutral Temperature for Venus, Earth, and Mars at Equator


Venus:
VTGCM equatorial temperatures and their diurnal variations for SMAX conditions: T (temperature at LAT = 2.5N, showing large day-night variations. Exospheric values range from a nightside minimum (104 K) to a dayside maximum (308 K), yielding a day-night contrast of 204 K. Cold mesopause temperatures (170-180 K) appear on the dayside over 100-125 km.

Earth:
TIEGCM equatorial temperatures and their diurnal variations for SMAX conditions: T (temperature at LAT = 2.5N, showing large day-night variations. Exospheric values range from a nightside minimum (1250 K) to a dayside maximum (1673 K), yielding a day-night contrast of 423 K. Cold mesopause temperatures (~160 K) appear on the dayside near 100 km.

Mars:
MTGCM equatorial temperatures and their diurnal variations for SMAX conditions: T (temperature at LAT = 2.5N, showing large day-night variations. Exospheric values range from a nightside minimum (150 K) to a dayside maximum (326 K), yielding a day-night contrast of 176 K. Cold mesopause temperatures (~113-135 K) appear on the dayside over 90-110 km.
