Satellite-Tracked Cumulus Velocities [PDF]
Journal of Applied Meteorology, 1975 The research indicates that extreme caution must be exercised in converting cloud velocities into winds. The motion of fair-weather cumuli obtained by tracking their shadows over Springfield, Missouri revealed that the standard deviation in the individual cloud motion is several times the tracking error.

Satellite Tracking of Cory's Shearwater Migration [PDF]
The Condor, 2000 Abstract Transmitters were attached to four adult male Cory's Shearwaters (Calonectris diomedea) caught at their breeding sites off Crete, Greece, in autumn 1998. The birds had left the Mediterranean by the beginning of December. Two were last recorded in the eastern tropical Atlantic in January/February.
