Temperatures in Jupiter's atmosphere derived from Galileo Probe decele
ration data increase from 109 kelvin at the 175-millibar level to 900
+/- 40 kelvin at 1 nanobar, consistent with Voyager remote sensing dat
a. Wavelike oscillations are present at all levels. Vertical wavelengt
hs are 10 to 25 kilometers in the deep isothermal layer, which extends
from 12 to 0.003 millibars. Above the 0.003-millibar level, only 90-
to 270-kilometer vertical wavelengths survive, suggesting dissipation
of wave energy as the probable source of upper atmosphere heating.
