Optical Flow derived winds from overlapping LEO granules

windflow_leo

A package for deriving atmospheric winds from overlapping granules of satellites in a LEO (low earth orbit) train formation, using dense feature tracking of CrIS retrievals of specific humidity (JPSS) or AVHRR imagery (MetOp).

This package runs inference on a pre-trained model based on WindFlow: Dense feature tracking of atmospheric winds with deep optical flow:
