Vertical structure Vertical structure of the atmosphere of Jupiter. Note that the pressure drops together with altitude. The Galileo atmospheric probe stopped transmitting at a depth of 132 km below the 1 bar "surface" of Jupiter. [3] The atmosphere of Jupiter is classified into four layers, by increasing altitude: the troposphere , stratosphere , thermosphere and exosphere . Unlike the Earth's atmosphere , Jupiter's lacks a mesosphere . [12] Jupiter does not have a solid surface, and the lowest atmospheric layer, the troposphere, smoothly transitions into the planet's fluid interior. [2] This is a result of having temperatures and the pressures well above those of the critical points for hydrogen and helium, meaning that there is no sharp boundary between gas and liquid phases. Hydrogen becomes a supercritical fluid at around 12 bars pressure. [2] Since the lower boundary of the atmosphere is ill-defined, the pressure level of 10 bars , at an altitude of about 90 km below the 1 bar with a temperature of around 340 K , is commonly treated as the base of the troposphere. [3] In scientific literature, the 1 bar pressure level is usually chosen as a zero point for altitudes—a "surface" of Jupiter. [2]
