Figure 45 Example of Composite Projection Geometry
COMP produces a single composite image of radar data from many radar sites.
COMP allows you to combine data from many dierent radars.
The advantages of compositing are:
• Expand the area of coverage to give forecasters the big picture.
• Fill-in blind spots caused by mountains or required sector blanking.
• Fill-in blind spots caused by scan strategy limitations (for example, not scanning to
high elevation angles).
• Simplify product management so users do not need to check multiple single-radar
images.
Types of Products for Compositing
Unlike other products, when you schedule a COMP product, IRIS does not make a product of
type COMP. Instead, it makes a composite of the input product and saves it as the input
product type.
