A number of physical and environmental constraints limit the
usefulness of conventional weather radar displays, often leading to
misinterpreted weather situations. However, the availability of
geographically overlapping radars networked together by a common data
transmission format, as currently exists in the United States,
facilitates the generation of a composite, or mosaic, image that
provides a more accurate weather presentation. This paper addresses
three major limitations of the conventional weather radar display and
describes how integrated returns from multiple weather radars can
significantly improve display quality and usefulness. An
introduction to the technical aspects of generating a composite
display is provided, along with an example to illustrate the
composite image concept.
