abstract = {Aeolus is the first Doppler wind lidar in space. It
provides unique high‐resolution measurements of horizontal
wind in the sparsely‐observed
upper‐troposphere/lower‐stratosphere (UTLS), with global
coverage. In this study, Aeolus’ ability to resolve
atmospheric gravity waves (GWs) is demonstrated. The
accurate representation of these small‐scale waves is
vital to properly simulate dynamics in global weather and
climate models. In a case study over the Andes, Aeolus GW
measurements show coherent phase structure from the surface
to the lower stratosphere, with wind perturbations > 10
ms−1, a vertical wavelength ∼8 km and an along‐track
horizontal wavelength ∼900 km. Good agreement is found
between Aeolus and colocated satellite, ground‐based lidar
and reanalysis data sets for this example. Our results show
that data from satellites of this type can provide unique
information on GW sources and propagation in the UTLS,
filling a key knowledge gap that underlies known major
deficiencies in weather and climate modelling.},
