2. IRIS Product Overview
IRIS provides features required for the operation of a weather radar network and distribution
of radar products, including local and remote radar control, signal processing, product
generation, and display.
The following tables provide an overview of the products supported in IRIS. The optional
products require additional licensing.

Product Description
BASE
Echo Base
BASE is used to determine the base of echoes.
BEAM
1)
Antenna Beam Pattern
BEAM is a full screen cross-section format image showing range-
averaged intensity in azimuth and elevation coordinates.
BEAM is used during calibration and alignment and to verify antenna
patterns.
CAPPI
Constant Altitude PPI
CAPPI is a horizontal cut at a selected altitude used for surveillance and
severe storm identification.
It is also useful for monitoring the weather at specific flight levels for air
traffic applications.
FCAST
1)
Forecast
FCAST is an array of direction and intensity vectors used to shift a
current weather display interactively.
GAGE
1)
The GAGE product stores reports from rain gage sensors for display and
use in product generation. These products are produced using an input
pipe from data sent by a weather station system.
Because
GAGE products are not produced from radar data, they do not
need to be configured or scheduled.
HMAX
Height of Maximum Intensity
Product
HMAX displays the height of the maximum data above each output pixel.
This product requires a volume scan.
LAYER
1)
LAYER can compute layer averages of any polar data types in the ingest
files.
LAYER can also convert to liquid first and compute VIL Density .
When computing VIL Density , the output is in g/m**3.
Lightening IRIS can import lightning data from a dedicated Vaisala lightning
detection network or from the GLD360 Global Lightning Detection
system.
MAX
Maximum Data
MAX shows the maximum data over each pixel as well as the East-West
and North-South maximum projects in side panes.
MLHGT
1)
Melting Level Height
MLHGT displays a map of the melting layer altitudes.
