“…It is well known that huge amount of energy is transferred from magnetosphere to thermosphere during geomagnetic storm conditions, mainly at the high latitude. There have been numerous studies, observations and/or simulations, on the causes and effects of magnetic storms (Bag, ; Bag et al, , ; Burns et al, ; Fuller‐Rowell et al, ; Huang et al, ; Lu et al, ; Prolss, ; Richards, ; Richmond & Lu, ; Smith, ; Verkhoglyadova, Meng, et al, , and references therein). The energy/momentum deposited causes large perturbations in the temperature, density, and composition through the processes of convection, particle precipitation, ionization, direct electric field penetration, ion‐drag forcing, and Joule and particle heating.…”

The nitric oxide (NO) radiative emission at 5.3 μm cools the thermosphere by conversion of solar energy into infrared radiation subsequently exiting thermosphere. It correctly serves as a natural thermostat. The NO 5.3-μm emission is even more important during geomagnetic storm events due to huge deposition of heat energy and momentum in the Earth's atmosphere. The Thermosphere, Ionosphere, Mesosphere Energetics, and Dynamics-Sounding of the Atmosphere using Broadband Emission Radiometry observation of NO 5.3-μm radiative emission is studied between ±55 ∘ geographic latitudes during eight geomagnetic storm events. Two events that occurred during 7-12 November 2004 (Dst = −374 nT) and 23-28 August 2005 (Dst = −184 nT) are analyzed in details. The variation of NO emission during other six storms is also presented. The NO volume emission rate (NO VER) shows an enhancement during storm events. The enhanced NO VER illustrates an equatorward movement with descending peak altitude as one moves toward the equator. The NO infrared radiative flux is calculated by integrating NO VER from altitude of 100 to 155 km. A local time hemispheric asymmetry in both NO VER and NO infrared radiative flux is observed during all geomagnetic storm events.

“…During a geomagnetic storm, the density distribution of the ions and neutral constituents in the upper atmosphere varies dramatically. Such variations may have signatures in airglow emissions (Bag et al., 2017; Leonovich et al., 2011; Makela et al., 2014).…”

“…In low earth orbit (LEO), between 200 and 700 km altitude, where space shuttles and the International Space Station (ISS) fly, atomic oxygen (AO) is the dominant atmospheric constituent under high vacuum 1–4 . AO is generated due to the photo‐dissociation of diatomic oxygen molecules by solar photons having a wavelength of ≤243 nm 5–7 .…”

[1][2][3][4] AO is generated due to the photo-dissociation of diatomic oxygen molecules by solar photons having a wavelength of ≤243 nm. [5][6][7] Although the AO density is very low in LEO, high incident fluxes of 5-eV oxygen atoms can be generated due to the orbital velocity 8 km/s.…”

To study the effects of low earth orbit (LEO) environment on film surface structure and resistance characteristics, reduced graphene oxide paper (rGOP) was irradiated by atomic oxygen (AO) in ground‐based simulation facility. A rough pits surface, chemical oxidation, and change in lamina thickness were found after AO exposure. The erosion yield under AO attack changed from 3.56 × 10−25 to 4.04 × 10−25 cm3/atom. The resistance data exhibited a linear relationship between R0/R and AO fluence, and the maximum AO detect fluence reached to 5 × 1019 atom/cm3 when rGOP thickness was 0.8 μm, which implies that greater thickness is expected to improve space service life of rGOP.
