Definition

The troposphere (from “tropos” = turning) is that portion of the atmosphere of a planet where the dominant means of energy transport is via convection and in which the temperature decreases with height due to adiabatic expansion, above the surface for a terrestrial planet or above an arbitrary level such as the top of the cloud decks for a giant planet like Jupiter. The temperature minimum at the top of the Earth’s troposphere is called the tropopause, above which is the stratosphere (in the case of the Earth, the giant planets and Titan) or the mesosphere (in the case of Mars and Venus).
