Observations of thermosphere and ionosphere changes due to the dissipative 6.5-day wave in the lower thermosphere

, 2015
In the current work, temperature and wind data from the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite during the years 2002–2007 were used to describe the seasonal variations of the westward propagating 6.5-day ...

The Impact of Polar Vortex Strength on the Longitudinal Structure of the Noontime Mid-Latitude Ionosphere and Thermosphere

Remote Sensing
Ground-based ionospheric, CHAMP/STAR, and GOCE satellite neutral density ρ observations under deep solar minimum conditions were used to find whether there is a dependence of longitudinal variations on polar vortex strength. Ionospheric stations at fixed-

Microsat‐2B Radiance Assimilation in the NCMRWF Global Forecasting System: Quantification of Analysis Improvement

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Indian Space Research Organization (ISRO) recently launched the meteorological satellite Microsat‐2B (M2B), which provides high‐resolution atmospheric moisture radiance observations, crucial for improving the predictability of numerical weather prediction (NWP) models.

Chemistry of the thermosphere

Termosfera je gornji dio atmosfere koji karakteriziraju iznimno visoke temperature. Proteže se od 80-90 km nadmorske visine do između 500 i 1000 km iznad površine Zemlje, ine i ju najširim dijelom atmosfere.
