(Note: the Japanese ADEOS-II mission was renamed to Midori-2 in mid-2003, though ADEOS-II is used in this site for historical reasons.) SeaWinds on ADEOS-II and SeaWinds on QuikSCAT are identical instruments and have been carefully cross-calibrated. The orbit phasing is such that they observe the same location at different local-times of day, however.

The wide swath and frequent overflights permit generation of a wide variety of SeaWinds Image products. For highest possible spatial resolution, multiple orbit passes are combined. These are the 'all pass' images. Since generally orbit passes of a given point on the Earth occur at nearly the same time of day, time-of-day studies are facilitated by computing images from ascending (morning) passes only, and descending (evening) passes only. For improved temporal resolution in the polar regions, daily local-time-of-day images have been generated.

Images are made both from the SeaWinds on ADEOS-II "egg" backscatter measurements and from the "slice" measurements. Generally, slice measurements yield higher spatial resolution but are noiser than egg measurements.
