Welcome to Odin-OSIRIS

Introduction

The OSIRIS instrument onboard the Odin spacecraft measures vertical profiles of spectrally dispersed, limb scattered sunlight from the upper troposphere into the lower mesosphere. On these pages you will find the user registration, documentation and browse imagery for Odin-OSIRIS Level 2 data products. OSIRIS has been in standard operation since November 2001 and routinely produces height profiles of O3, NO2 and stratospheric aerosols. The Odin satellite also runs a sub-millimeter radiometer (SMR) that measures profiles of many other atmospheric species.

The OSIRIS spectrograph measures from 274 nm to 810 nm with a single line of sight that is scanned through a range of tangent altitudes. Each scan typically ranges from 7 km to 65km or from 7 km to 100 km depending upon the mode and takes between 40 and 70 seconds to acquire.

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 with almost complete coverage.

The Odin orbit is a sun synchronous orbit at 6 pm/6 am local time. This restricts OSIRIS sunlit observations to the Northern hemisphere in May, June, July August and the Southern hemisphere in November, December, January and February.
