The Ozone Monitoring Instrument (OMI) will measure the daily global distribution of O3, NO2, BrO, SO2, and HCHO with unprecedented spatial resolution (pixel size of 13x24 km2 subsatellite). To detect the total column amount of these (tropospheric) trace gases accurately, the cloud pressure and effective cloud fraction in the same pixel are needed. This cloud information is retrieved operationally with a new algorithm using the O2-O2 absorption band at 477 nm (O2-O2 is a collision complex of oxygen).
