What is What is OdinOdin?? OdinOdin is a joint Swedish/Canadian/French/Finnish
small research satellite mission combining investigations in both
Aeronomy & Astronomy
The AstronomyAstronomy studies focus on the chemistry of the interstellar medium, comets and star formation
The AeronomyAeronomy (Atmospheric Science) studies focus on the chemistry and dynamics of the Earth's stratosphere and
mesosphere
OSIRISOSIRIS on
There are two instruments on OdinOdin:
(1)(1) A Swedish SSubub-MMillimeter illimeter RRadiometer (adiometer (SMRSMR)) which is used for both astronomy and aeronomy
(2)(2) A Canadian OOptical ptical SSpectrograph pectrograph && IR IIR Imager mager SSystem (ystem (OSIRISOSIRIS) )
which is used for atmospheric studies only
OSIRISOSIRIS on
The Canadian OSIRISOSIRIS instrument on OdinOdin includes a limb viewing grating spectrometer
which measures the radiances of limb scattered sunlight in the wavelength range
300 - 800 nm

The OSIRISOSIRIS scattered sunlight spectra are used to obtain vertical distributions of O3, NO2, OClO & BrO, with aerosol extinction and temperature &
pressure information, throughout the stratosphere and mesosphere

• OdinOdin was successfully
launched on a Russian
START 1 ICBM from Svobodny,
Siberia, on
20th Feb, 2001

• We at York are now analyzing the OSIRISOSIRIS
data

So what are we getting from OSIRIS OSIRIS ?

Sample scan from about 10 to 90 km in tangent height

OSIRIS total ozone column densities (in Dobson units) measured over the S.H. on 25th September 2002 (without tropospheric component)

But OSIRISOSIRIS does more than TOMS and other total ozone mappers
OSIRISOSIRIS also measures the vertical profile of ozone not just the total column density of ozone
i.e., OSIRISOSIRIS adds an important extra dimension - height
OSIRISOSIRIS on
OSIRIS ozone number densities at 10 km measured over the S.H. on 25th September 2002
OSIRISOSIRIS on
OSIRIS ozone number densities at 15 km measured over the S.H. on 25th September 2002

OSIRIS ozone number densities at 20 km measured over the S.H. on 25th September 2002

OSIRIS ozone number densities at 25 km measured over the S.H. on 25th September 2002

OSIRIS southern hemisphere ozone
number density profiles measured on 3 orbits
passing through the “ozone hole” region
on 24/25 Nov 2001
The arrows indicate the highest latitude profiles
(82ºS)which were measured at
longitudes of ~110, 90 and 70ºE respectively (see previous slide)

Some OdinOdin facts:
• The expected mission lifetime is 2 years
• The total OdinOdin platform mass is ~235 kg235 kg the total payload mass is ~75 kg75 kg and the OSIRISOSIRIS mass is ~10 kg10 kg
• The total expected mission cost over the first two years is $65$65 million US = 1$/second
