The Doppler Wind Experiment on the Galileo probe provided the first in situ data on wind speeds in Jupiter's atmosphere. Initial analysis of the results indicated that wind speeds increase with depth, rather than decaying to zero below the cloud tops or remaining relatively constant as had previously been assumed. But this earlier analysis was subject to several potential sources of error, as highlighted by the fact that wind speeds measured at the cloud tops did not seem to match those… Expand

Galileo Doppler Measurements of the Deep Zonal Winds at Jupiter
TLDR
Analysis of the probe relay link frequency allows direct measurements of the speed of Jupiter's zonal winds beneath the cloud tops, which severely constrain dynamic modeling of the deeper layers and begin to rule out many shallow weather theories. Expand

TLDR
Two Earth-based wind estimates are less sensitive to descent trajectory errors than estimates based on probe-orbiter Doppler measurements, and both show high wind speeds at all depths sampled. Expand
