Image Compositing
The mosaics of all available CZCS data collected on a given day form the
building blocks for all longer-term averages. Where more than one pass
overlaps, data for that area are averaged, but the number of passes averaged at
any one point on the Earth to form the composite varies greatly. Here, the
results of the compositing process can be seen with daily, weekly, monthly, and
seasonal composites displayed. Note the increased geographical coverage, and
spatial smoothing that occurs as the time-scale increases.
