TL;DR: The DEEPWAVE (deep-propagating wave experiment) campaign was designed for an airborne and ground-based exploration of gravity waves from their tropospheric sources up to their dissipation at high altitudes as mentioned in this paper.
Journal ArticleDOI
NRLMSIS 2.0: A Whole-Atmosphere Empirical Model of Temperature and Neutral Species Densities
J. T. Emmert,D. P. Drob,J. M. Picone,David E. Siskind,M. Jones,M. G. Mlynczak,Peter F. Bernath,Peter F. Bernath,Xinzhao Chu,Eelco Doornbos,Bernd Funke,Larisa Petrovna Goncharenko,Mark E. Hervig,Michael J. Schwartz,Patrick E. Sheese,Fabio Vargas,Bifford P. Williams,Tao Yuan +17 more
TL;DR: NRLMSIS® 2.0 as mentioned in this paper is a major, reformulated upgrade of the previous version, NRLMSISE•00, which couples thermospheric species densities to the entire column, via an effective mass profile that transitions each species from the fully mixed region below ~70 km altitude to the diffusively separated region above ~200 km.
