Coupled variations of stratospheric and mesospheric temperatures derived from SABER

The SABER instrument on the TIMED satellite has been making high quality measurements of temperatures spanning the stratosphere and mesosphere (~20-100 km) during 2002-2014. We utilize SABER data to examine variability of middle atmosphere temperatures and vertical coupling across a range of time scales. SABER data show evidence for QBO modulation of temperatures extending into the mesosphere, along with global-scale transient events that span the stratosphere and mesosphere. SABER measurements are also combined with Stratospheric Sounding Unit (SSU) data over 1979-2005 (from improved merged data sets) to provide an update of long-term stratospheric temperature variations covering 1979-2014.
