Abstract The photochemistry of NO, N(2D) and N(4S) and results of recent space measurements of their density distribution are discussed. In particular, the role of the reaction between metastable N(2D) atoms and O2 as a source of O(1D) is discussed in the light of laboratory and aeronomical observations.

Theoretical thermosphere models
Advances in Space Research, 1985Abstract The major solar and geomagnetic energy and momentum inputs which drive the thermosphere have been incorporated in theoretical and numerical three-dimensional and time-dependent models of the thermosphere. Data from recent satellites and from ground-based facilities have been used to test these numerical simulations.

Abstract The Earth's mesosphere and lower thermosphere are the least explored regions of the Earth's atmosphere. The observations that have been made in this region, however, indicate that it is a dynamically active region, especially the polar lower thermosphere where most of the auroral energy that impacts the Earth's atmosphere is deposited.

Ground state of the thermosphere and substorm time thermospheric response
The thermospheric composition (O/N2 ratio and NO) condition represents the state of the thermosphere. Significant changes in thermospheric composition and neutral wind are often observed during non-storm time (e.g. a weak substorm on May 29, 2023) due to continous energy and momentum input from solar wind to the geospace.  It is challenging toYongliang Zhang +4 more
