Long-term observations of atmospheric gravity waves from TIMED-SABER

Atmospheric gravity waves play a key role in transmitting energy and momentum from the lower atmosphere to the middle and upper atmosphere and ionosphere. Unlike global-scale waves such as atmospheric tides, these waves are relatively localized and as such global-scale observations are required to determine their influence around the planet and how this varies in response to solar and atmospheric weather drivers. TIMED-SABER observations of atmospheric temperature have been available since 2002 and new analysis techniques allow for the identification of gravity waves in these data. Here we present an analysis of the SABER gravity wave observations over this long-term dataset, their variations around the globe and changes in response to atmospheric and solar influences.
