Abstract
SWIFT is a small (< 85 kg, approximately 0.5 m3, < 100 W) satellite instrument which is designed to accurately measure global horizontal winds and ozone concentrations in the stratosphere. SWIFT is similar to the highly successful WINDII instrument currently operating on the UARS satellite. Both use a field-widened Michelson interferometer set at high path difference to image the Doppler shift of atmospheric emission. The data set provided by SWIFT will provide essential input to the next generation of Numerical Weather Prediction (NWP) models which are currently being developed by meteorological organizations worldwide. SWIFT is currently a leading candidate to fill the foreign instrument opening for the NASDA GCOM-A1 mission, providing highly complimentary data to the ODUS and SOFIS instruments. SWIFT allows direct measurement of stratospheric dynamics and high vertical resolution ozone profiling to maximize the scientific return for this mission.
