File Times height AGL antenna position obs
F :06-22:12 ~1400 m down multiple humidity jumps, even at 1400 m; nice echo plumes
F :20-22:25 ~600 m up 2 dryline plumes emerge from a series of q-discontinuities
F :42-22:48 ~200 m up single dryline, tilting to the W as if propagating like a density current
F :24-23:30 ~1400 m down 2 drylines, the E one is best defined - we can try dual-Doppler
F :33-23:39 ~800 m down 2 drylines, retreating W and diverging from each other
F :44-23:52 ~200 m up 2 well-defined drylines, retreating westward, esp the western one
