thermosphere Usage Examples

Adjective modifier

  • upper: Differences only become significant above about 70km, but are very large in the upper mesosphere/lower thermosphere.
  • low: The results will show how far planetary waves penetrate into the lower thermosphere under " direct " forcing.
  • terrestrial: The modeling work at APL goes back thirty years for the terrestrial thermosphere.
  • Martian: Three dimensional modeling of the Martian thermosphere and ionosphere at UCL.

Modifies a noun

  • wind: Time and scale size of planetary wave signatures in the ionospheric f region: Role of the geomagnetic activity and mesosphere/lower thermosphere winds.
  • region: These studies involve measuring reaction rate coefficients at the low temperatures characteristic of the mesosphere/lower thermosphere region.

Noun used with modifier

  • mesosphere/lower: These studies involve measuring reaction rate coefficients at the low temperatures characteristic of the mesosphere/lower thermosphere region.
  • high-latitude: This has indicated the presence of atmospheric gravity wave signatures in the high-latitude thermosphere.
