Satellite Ozone Profiles From Omi: Daily Global Coverage At 50x50 Km2 Resolution
Abstract
In June 2003, the NASA EOS-AURA satellite is scheduled for launch, as part of the successful Earth Observing Satellite series, with onboard the Ozone Monitoring In- strument (OMI). OMI is a nadir-viewing UV-VIS instrument with a 2600 km wide swath, guaranteeing daily global coverage. The nadir ground pixel size for which ozone profiles will be delivered is approximately 50X50 km2. This combination of daily global covarage and excellent spatial resolution is unprecedented and is expected to provide an enhanced view of processes involving ozone on a global scale. The algorithm used for the retrieval of ozone profiles is based on past experience with the GOME satellite and is further developed along with the ozone profile algorithm for GOME-2. The design of OMI improves on GOME on several points: OMI is not sensitive to the polarisation of the detected light and its measurements do not suffer from spatial aliassing. This will give a higher accuracy and a better vertical resolution of the ozone profile.
We present a description of the algorithm and the results of an comprehensive error analysis.- Publication:
