AB: The Halogen Occultation Experiment (HALOE) instrument on board the Upper Atmospheric Research Satellite (UARS) has been operating without flaw since it was activated on October 11, 1991. The experiment uses the instrument methods of gas filter and broad-band radiometry and the solar occultation technique to measure vertical profiles of O3, HCl, HF, CH4, H2O, NO, NO2, extinction due to aerosols, and temperature versus pressure. The HALOE mission has provided the longest remotely sensed, continuous, and near global record of HCl, HF, CH4, and NO measurements in existence. The data have been used to examine transport and chemistry throughout the stratosphere and in the lower mesosphere, validation of other remote sensors, and also to infer how the circulation strength in the middle atmosphere has changed during the UARS time period. We present an overview of the HALOE mission, some of the significant science highlights, comparison's with other instruments, and preliminary results of the next public release version which will extend the H2O profile well into the troposphere. Science highlights include the HALOE derived total Cl and F trends near the stratopause, the tropical tape-recorder signal in H2O, O3 trends, and ozone recovery.
