1. Make a diagram of the layout that you want, similar to the following figure.
Compare this to the elevations in your task to see if you have a sensible resolution,
especially in the upper parts of your
MAX box.
Layer Top = 16 km
Layer Bottom = 0 km
Center of Top Pixel
at 15.75 km
Center of Bottom
Pixel at 0.25 km
E–W Maximum Projection
Radar
West 220 Pixels East
South
224 Pixels
North
Max Range
= 220 km
Side Panel Resolution
= 32 Pixels
2. Select Type > MAX .
3. Select a Product Name that is mnemonic.
For example, Z_0_16_220 indicates that the product covers the layer 0 ... 16 km (0 ...
9.9 mi) to a range of 220 km (136.7 mi).
4. Select the TASK Name .
The associated TASK Name must correspond to a volume scan task.
At least 2 elevation angles are required.
5. In Data:Display , select the input data.
Available data types include
dBT
,
dBZ
,
dBZc
,
V
,
Vc
,
W
,
ZDR
,
ZDRc
, and
Kdp
.
Rainrate can be output for the appropriate types.
6. Define the Max Range .
The Max Range corresponds to the span of the image from the radar to the edge of the
picture in the East-West direction.
In the example, the range of 220 km (136.7 mi) is covered by 120 pixels to yield 2 km
(1.2 mi) per pixel resolution.
7. Select the Layer Top and Layer Bottom to the nearest 100 m (328 ft 1 in).
When selecting the layer top value, remember the maximum data height allowed for
your system as configured in the
Setup utility.
In the example, the layer spans 0 to 16 km (0 to 9.9 mi). The corresponding side panel
resolution is set to 32 pixels so that each pixel represents 0.5 km (0.3 mi). The center of
the bottom pixel is at 0.25 km (0.2 mi) height and the center of the top pixel is at
15.75 km (9.8 mi) height.
