Arctic winter observations in 2013 by the Solar Occultation for Ice Experiment (SOFIE) show significant transport from the lower-thermosphere to the stratosphere of air enriched in nitric oxide, but depleted in water and methane. The transport is triggered by the Stratospheric Sudden Warming (SSW) on January 11 and is continuously tracked for over three months. Ultimately, evidence for lower thermospheric air is seen at 40 km in mid-April. Area integrated NO fluxes are compared with previous events in 2004, 2006, and 2009, to show that this event is the 2nd largest in the past 10 years. The SOFIE data are combined with a meteorological analysis to infer descent rates from 40–90 km. The descent profile initially peaks near 75 km, shifting downward by approximately 5 km per 10 days. Our work demonstrates the utility of SOFIE tracer measurements in diagnosing vertical transport from the stratosphere to the edge of space.
