The quiet nighttime low-latitude ionosphere as observed by TIMED/GUVI

In this paper, we examine the nighttime ionosphere climatology structure in the low latitude region and discrepancies between Global Ultraviolet Imager (GUVI) observations and the IRI model predictions using (1) the magnetic zonal mean of electron number density as a function of altitude and magnetic latitude, (2) vertical electron density profiles at various levels of F10.7 index, (3) nighttime descent and magnitude decrease of the ionosphere, (4) point-to-point comparisons of F-peak height (hmF2) and density (NmF2), and ...

Wave structures of the plasma density and vertical E$\times$ B drift in low-latitude F region

We investigate the seasonal, longitudinal, local time (LT), and altitudinal variations of the F region morphology at low latitudes using data from the first Republic of China satellite (ROCSAT-1), Global Ultraviolet Imager (GUVI), on board the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite, and the Defense Meteorological Satellite Program (DMSP) F13 and F15 satellites. Signatures of the longitudinally periodic plasma density structure emerge before 0900 LT. The wave structure is established befo ...

Remote sensing of the nighttime ionosphere with the TIMED Global Ultraviolet Imager

The Global Ultraviolet Imager (GUVI) aboard the TIMED spacecraft monitors ultraviolet radiation from the terrestrial atmosphere in five spectral regions. Measurements of 1356-angstrom radiation on the Earth\textquoterights limb are part of this dataset. The primary source of this 1356-angstrom radiation on the night side is the recombination of molecular oxygen ions and electrons. In this work, we present a method for inferring vertical electron density profiles and total electron content (TEC) from the GUVI night-side li ...
