    • NRLMSIS 2.1: An Empirical Model of Nitric Oxide Incorporated Into MSIS 

      Emmert, John T.; Jones Jr, M.; Siskind, David E.; Drob, D. P.; Picone, J. M.; Stevens, M. H.; Bailey, Scott M.; Bender, Stefan; Bernath, Peter F.; Funke, Bernd; Hervig, Mark E.; Pérot, Kristell (Peer reviewed; Journal article, 2022)
      We have developed an empirical model of nitric oxide (NO) number density at altitudes from ∼73 km to the exobase, as a function of altitude, latitude, day of year, solar zenith angle, solar activity, and geomagnetic activity. ...

    • Transport of Nitric Oxide Via Lagrangian Coherent Structures Into the Top of the Polar Vortex 

      Harvey, Lynn V.; Datta-Barua, Seebany; Pedatella, Nicholas M.; Wang, Ningchao; Randall, Cora E.; Siskind, David E.; van Caspel, Willem Elias (Peer reviewed; Journal article, 2021)
      The energetic particle precipitation (EPP) indirect effect (IE) refers to the downward transport of reactive odd nitrogen (NOx = NO + NO2) produced by EPP (EPP-NOx) from the polar winter mesosphere and lower thermosphere ...
