abstract = "{We use the Global Self-consistent Model of the Thermosphere, Ionosphere
and Protonosphere (GSM TIP) as the first-principle calculation
of the physical system state, the quick-run ionospheric electron
density model (NeQuick) as the climatology background, and the
International Reference Ionosphere-based Real-Time Assimilative
Model for a global view of the ionospheric weather during a
quiet period of the December 2009 solstice. The model
computations are compared to the Constellation Observing System
for Meteorology, Ionosphere, and Climate (COSMIC) radio
occultation profiles, CHAMP and Gravity Recovery and Climate
Experiment in situ densities, and GPS total electron content
(TEC). It is shown that the plasma density in the ionosphere is
generally larger in the American/Atlantic longitudinal sector at
any local time. The high-latitude density enhancements are
visible in the GSM TIP output at different altitudes but are not
reproduced by the NeQuick empirical model. Given that
observational data confirm an existence of the high-latitude
areas where ionospheric densities are elevated in the altitude
range between 300 and 480 km, we conclude that the
N$_{m}$F$_{2}$ maximum in the GSM TIP output can be trusted.
Indeed, such high-latitude N$_{m}$F$_{2}$, ionospheric electron
content, and TEC maxima in the American longitude sector form on
the proper places as shown by the GSM TIP data, COSMIC and GPS
observations. According to our results, the high-latitude
maximum of N$_{m}$F$_{2}$ (1) manifests itself only when the
integration over LT or UT of the global maps for 22 December
2009 includes nighttime, i.e., supporting an argument of its
close association with the Weddell Sea Anomaly, and (2) also
appears in the N$_{e}$ distribution at altitudes above the
F$_{2}$ peak.}",
