The E-region wind interferometer, ERWIN, was refurbished and moved from Resolute Bay to the Polar Environment Atmospheric Research Laboratory (PEARL) in Eureka (80N) in the winter of 2008. ERWIN is a field widened Michelson interferometer which measures winds in the E-region using Doppler shifts in hydroxyl, oxygen green line and O2 airglow emssions. The referbished instrument is constructed around the old interferometer and includes imaging capabilities using a CCD detector and an optical system which allows simultaneous viewing in four directions and zenith. The instrument operates by seqentially viewing the three emissions. The observation cadence for the three emissions is ~2 minutes making this the fastest wind measuring instrument in the world for the mesopause region. An overview of the instrument operation and results from the first year of observations (including winds during stratospheric warmings) are presented.
