Fig. 11From: Numerical forecast of the upper atmosphere and ionosphere using GAIAStandard deviation as a function of LT = UT + 9 h, from the a GAIA simulation and b observation at the 29° N latitudinal band, and from the c GAIA simulation and d observation at the 41° N latitudinal band. Color distinguishes four seasons: February–April (black), May–July (blue), August–October (green), and November–January (orange)Back to article page
