Please note that due to a processing error Level2 data covering the period May 2009 to July 2014 should be treated with caution. Simply put, files with names referring to a particular orbit do not necessarily contain data from that orbit. The problem becomes progressively worse with time. Reprocessing of this period will commence soon. Watch this space for more details!
The Odin satellite was launched in February 2001 and was designed to combine two scientific disciplines on a single spacecraft for studying of star formation and the early solar system (astronomy) and the mechanisms behind the depletion of the ozone layer in the Earth's atmosphere and the effects of global warming (aeronomy).
The satellite has been used as a true observatory in order to best respond to scientific challenges. The astronomy mission was successfully concluded in the spring of 2007 and since then the satellite has been used exclusively for studies of the Earth’s atmosphere. During the first three years of the Odin mission, when both astronomy and aeronomy observations were conducted, the available observing time was shared equally between the two disciplines.
SANOMA is an empirical model of nitric oxide in the upper mesosphere and lower thermosphere, based on Odin/SMR measurements. It provides the NO number density as a function of magnetic latitude (from -82.5 to +82.5 degrees) and altitude (from 85 to 118 km) for any day under consideration. Basic instructions on how to use this model, as well as the associated coefficients, are available on this web page. These files are provided in MATLAB format. The coefficients are also available in text format for those who do not have MATLAB.
We refer the users to the article "An empirical model of nitric oxide in the upper mesosphere and lower thermosphere based on 12 years of Odin-SMR measurements", by J. Kiviranta, K. Pérot, P. Eriksson and D. Murtagh, published in Atmospheric Chemistry and Physics in 2018, for further details. If you wish to use this model, or for any other question about it, please contact Kristell Pérot (firstname.lastname@example.org),
Since the launch of Odin in 2001 the Department of Earth and Space Sciences at Chalmers has been responsible for processing the Level2 product. In september 2015 ESA/SPPA decided to support the reprocessing of the Odin/SMR data set, which is now in progress.
The Odin mission has been supported by ESA since 2007. Odin is a part of ESA's Third party misson program within its Earthnet Programme.
The mission scientist for ODIN/SMR is Prof. Donal Murtagh (Chalmers) and ESA's contact is Angelika Dehn
