Description
The Optical Spectrograph Infrared Imager System (OSIRIS) is an imaging spectrometer developed by researchers at the University of Saskatchewan that is currently on board the Swedish Odin satellite. OSIRIS conducts ozone measurements of the atmosphere by measuring the spectrum of limb-scattered sunlight, which are then later processed to retrieve vertical atmospheric profiles of ozone. Since the launch of OSIRIS, CubeSat missions are increasingly becoming commonplace for use in Earth-atmosphere science and remote sensing. However, CubeSat missions that perform remote sensing or Earth-atmosphere experiments typically conduct observations in nadir geometry, and very few CubeSat missions to date use the limb geometry for these observations. There are currently no ozone CubeSat missions in development that measure ozone in the limb geometry. This presentation will discuss the feasibility of a CubeSat-sized ozone-sensing instrument in the limb geometry. Results from retrieval simulations that use an instrument model and a radiative transfer model to simulate a 12U, 6U, and 3U sized OSIRIS payload will be discussed.
