Implication

Satellite observation study reports global upper-atmosphere neutral wind profiles in the mesosphere and lower thermosphere, demonstrating robust detection of diurnal and semidiurnal migrating tides.

Key Points

To review the instrument design, on-orbit performance, and data processing methods of the TIMED Doppler Interferometer (TIDI), and summarize initial global MLTI neutral wind observations.
Measured daytime and nighttime neutral winds in the 85–105 km altitude range using a limb-scanning Fabry-Perot interferometer targeting the molecular oxygen (0-0) band.
Combined orthogonal line-of-sight views from four scanning telescopes using a Circle-to-Line Interferometer Optic onto a single detector to construct vector wind altitude profiles.
Adjusted instrumental operating modes and inversion algorithms to mitigate data impacts from on-orbit white light leakage and optical ice deposition.
Extracted migrating diurnal and semidiurnal tides across multiple satellite yaw cycles using resolved MLTI vector wind profiles.
Demonstrated qualitative and directional consistency between TIDI-derived winds and predictions from the Global Scale Wave Model, UARS HRDI instrument data, and ground-based meteor radar observations.
