| Zusammenfassung |
| The Odin satellite, launched in February 2001, provides global or near-global coverage of
various atmospheric constituents with high vertical resolution. The two onboard instruments,
the Sub-Millimetre Radiometer (SMR) and the Optical Spectrograph and Infra-Red Imager
System (OSIRIS), are co-aligned and give reliable profiles of O3, NO2, N2O, HNO3, H2O,
CO, etc. A new approach, where data from both OSIRIS and SMR are merged using a
chemical box model to construct an Odin proxy NOy product, has recently been
developed.
Climatologies of these data sets, based on multi-year statistics, have proven to be very
useful for validating Chemical Transport Models (CTMs) and Chemistry Climate Models
(CCMs). Longer-lived species such as N2O and CO have been used to test whether
atmospheric transport is realistically represented by/in the models. The presentation will
describe the relevant Odin climatologies and provide examples of comparisons to
state-of-the-art chemistry climate models such as the Canadian Middle Atmosphere
Model. |
