• A global view of stratospheric gravity wave hotspots located with Atmospheric Infrared Sounder observations (2012, background): “Global estimates of gravity wave momentum flux show that this region is an important source for waves contributing to Southern Hemisphere wind drag [Ern et al., 2004; Alexander et al., 2008; Hertzog et al., 2008; Ern et al., 2011].”
• Recent developments in gravity‐wave effects in climate models and the global distribution of gravity‐wave momentum flux from observations and models (2010, methodology): “CRISTA values are larger, due partly to the sensitivity/aliasing corrections applied in Ern et al. (2004), partly to the longer vertical wavelengths included in the CRISTA analysis and, as discussed in the next section, partly to intermittency and the different averaging times (1 week versus 1…”
• A comparison between gravity wave momentum fluxes in observations and climate models (2013, methodology): “Recently, new methods for deriving gravity wave momentum fluxes from global observations have been developed (Vincent et al. 1997; Ern et al. 2004;Alexander et al. 2008; Hertzog et al. 2008).”

• Global estimates of gravity wave momentum flux from High Resolution Dynamics Limb Sounder observations (2008, background): “The waves identified in our HIRDLS analysis do not show the flattened distribution that indicated severe undersampling in CRISTA at high latitudes [Ern et al., 2004].”
• Retrieval of stratospheric temperatures from Atmospheric Infrared Sounder radiance measurements for gravity wave studies (2009, methodology): “Global estimates of wave pseudomomentum flux have been made using satellite observations [ Ern et al., 2004, 2006; Alexander et al., 2008], however these had large uncertainties because the propagation directions of the waves could not be determined.”
• The deep propagating gravity wave experiment (deepwave): an airborne and ground-based exploration of gravity wave propagation and effects from their sources throughout the lower and middle atmosphere (2016, background): “Such measurements nevertheless reveal the larger-scale responses to multiple sources, define the global hotspots of GW activity and their seasonal variations, and on occasion capture very strong GW responses under ideal viewing conditions (e.g., Dewan et al. 1998; Eckermann and Preusse 1999; Ern et ”

• Modeling the effects of gravity wave momentum deposition on the general circulation above the turbopause (2009, background): “For instance, satellite measurements of temperature fluctuations provide a good global coverage of average GW activity [Ern et al., 2004; Alexander et al., 2008], while ground-based lidar measurements [e.g., Yang et al., 2008] offer high temporal resolution but poor global coverage.”

Part II: Results from the Vorcore Campaign in Antarctica (2008, methodology): “Balloonborne absolute momentum fluxes ( 0 u w ) were furthermore multiplied by (1 f 2/̂2) to compute the wave pseudomomentum flux, which is the quantity used in Ern et al. (2004, 2006).”

• On the origins of mesospheric gravity waves (2009, background): “…satellite observations capture a global image of gravity waves and provide useful information on the momentum flux in the stratosphere [Ern et al., 2004; Alexander et al., 2008], it is hard to examine the wave propagation because of the observational filter problem [Alexander, 1998].”
