The International Outer Planets Watch (IOPW) is an informal organization of astronomers and planetary scientists who are interested in the study of the Solar System's giant planets, their atmospheres, satellites, rings, magnetospheres, aurorae, and other phenomena. For this purpose, the International Outer Planets Watch has a Steering Committee and six discipline groups.

The Atmosphere Discipline of the IOPW is devoted to coordinate and encourage observations of the atmospheres of the giant planets and their satellites, from the Earth and from space, with an emphasis on time-variable phenomena.
