Abstract. The first three Arctic winters of the ACE mis-sion represented two extremes of winter variability: Strato-spheric sudden warmings (SSWs) in 2004 and 2006 were among the strongest, most prolonged on record; 2005 was a record cold winter. Canadian Arctic Atmospheric Chem-istry Experiment (AC...

Description
Summary:Abstract. The first three Arctic winters of the ACE mis-sion represented two extremes of winter variability: Strato-spheric sudden warmings (SSWs) in 2004 and 2006 were among the strongest, most prolonged on record; 2005 was a record cold winter. Canadian Arctic Atmospheric Chem-istry Experiment (ACE) Validation Campaigns were con-ducted at Eureka (80 ◦ N, 86 ◦ W) during each of these win-ters. New satellite measurements from ACE-Fourier Trans-form Spectrometer (ACE-FTS), Sounding of the Atmosphere using Broadband Emission Radiometry (SABER), and Aura Microwave Limb Sounder (MLS), along with meteorological analyses and Eureka lidar temperatures, are used to detail the meteorology in these winters, to demonstrate its influence on transport, and to provide a context for interpretation of ACE-FTS and validation campaign observations.
