First daytime thermospheric wind observation from a balloon-borne Fabry-Perot interferometer over Kiruna (68N)
HIWIND (High altitude Interferometer WIND Observation) is the first balloon Fabry-Perot interferometer (FPI) to achieve successful thermospheric wind measurement for both day and night. By flying at ∼40 km altitude, HIWIND avoids the high solar scattering background and enables daytime remote sensin...
