Vaisala IRIS - System Manager Preparations for Composites

• Average
Average uses the average of the available data. This is a poor choice if you are trying to
cover blocked regions.
• Priority
Priority uses data from the available radar that is highest on the site list defined in the
COMP Product Configuration Menu.
• Nearest
Nearest uses data from the radar that is at the shortest distance away. The data from
the radar that is further away is ignored.
• Weighted
For weighted, the assigned value at a location is determined by a weighted average
from all the radars detecting a signal at that location.
The weighting is inversely proportional of the distance to the radar site. Data from
closer radar sites have a bigger impact to the final value than data from sites farther
away.
You can choose the combining algorithm in the COMP Product Configuration Menu.
Output
There is no COMP product. The output of a COMP PPI is a PPI product with the name that is
assigned in the COMP Product Configuration Menu.

System Manager Preparations for Composites
To support composite creation, the system manager must set-up the following items in
advance. In many cases, these are pre-configured for your system.
• Configure the radar sites in IRIS Setup > General. See IRIS and RDA Utilities Guide.
• Configure the projection in IRIS Setup > projection.
