OSIRIS is one of two instruments on the Odin satellite, launched February, 2001 (the other instrument being a sub-mm radiometer) into a sun-synchronous, 6 pm\/6 am local time orbit at 600\u00a0km. This restricts OSIRIS sunlit observations to the Northern hemisphere in May, June, July and August, and the Southern hemisphere in November, December, January and February. Global coverage from 82\u00b0S to 82\u00b0N occurs on the months adjoining the equinoxes. OSIRIS measurements began November, 2001 and continue to the present.

Each scan typically ranges from 7\u00a0km to 65\u00a0km and takes 40 seconds to acquire. The measurements are used to produce height profiles of O3, NO2, and stratospheric aerosols.The Odin satellite was operated until June 2007 as a joint mission between astronomy and aeronomy disciplines. 50% of the total observation time was dedicated to each discipline where time was split into 1 day segments. Odin has operated as a purely aeronomy mission since June, 2007, and continues to the present, with almost complete coverage.OSIRIS is a Canadian instrument, operated by the Canadian Space Agency. The mission PI is Dr. Doug Degenstein, University of Saskatchewan. Odin is operated by the Swedish Space Corporation, with funds from the European Space Agency as a Third Party Mission.
