Composition and temperature data from satellite measurements and from radar backscatter
observations show that dynamics is a major key in our understanding of the upper …

Long‐lived or metastable excited states of various atoms and molecules in the
thermosphere provide reservoirs for the temporary storage of a considerable portion of the …

The influence of breaking gravity waves on the dynamics and chemical composition of the
60‐to 110‐km region has been investigated with a two‐dimensional dynamical/chemical …

The quality of the retrieved temperature‐versus‐pressure (or T (p)) profiles is described for
the middle atmosphere for the publicly available Sounding of the Atmosphere using …

Most environmental satellite radiometers use solar reflectance information when it is
available during the day but must resort at night to emission signals from infrared bands …

The Atmospheric Ultraviolet Radiance Integrated Code (AURIC) is a software package
developed under the sponsorship of the Air Force Phillips Laboratory/Geophysics …

A general circulation model has been developed for the atmosphere above 97 km. It uses a
5° latitude× 5° longitude grid and 24 vertical levels in increments of 0.5 scale height. The …

Gravity waves (disturbances to the density structure of the atmosphere whose restoring
forces are gravity and buoyancy) comprise the principal form of energy exchange between …

Nitrous acid (HONO) is a significant precursor of atmospheric “detergent” OH radicals and
plays a vital role in tropospheric chemistry. The current knowledge about daytime HONO …

The National Center for Atmospheric Research thermosphere‐ionosphere general
