Research questionHow can one geostationary satellite provide dense 3D winds without NWP-dependent heights or stereo overlap?Traditional atmospheric motion-vector retrievals can be computationally costly and sparse, while their height estimates depend on numerical weather prediction states. Stereo observations provide geometric height information but require suitable views from multiple satellites and have limited coverage.

Latest papersRecent research connected to this question, newest first.Distilling deep optical flow stereo methods to retrieve dense three-dimensional wind fieldsThe study uses GEO imagery and distills a GEO-GEO or GEO-LEO stereo teacher into a single-satellite student that retrieves wind fields and emulates the teacher’s chi-square and height uncertainties. Evidence is reported against radiosondes, operational atmospheric motion vectors, ERA5 reanalysis, and EarthCARE cloud profiles; results vary by infrared band, with gains in water-vapor bands and degradation in the 11.2 μm band.research paper · Sep 2, 2026
