3. Input Product Type and Name to define the input product, that is, the product that you
want to "dwell" together.
You can select any of the following product types:
• BASE
• CAPPI
• HMAX
• PPI
• RAIN1
• SRI
• TOPS
• VIL
• WARN
When combining WARN products, the centroid characteristics of all the input products
are combined together. Therefore, most of the menu features in the DWELL product are
disabled, except the DWELL time selection.
4. Define the dwell Time.
This is the time period in minutes for which products are dwelled together.
For example, when a new PPI product is created or received, this and all PPI products
within the last 10 minutes are included in the DWELL PPI product.
5. DWELL products using PPI as an input product, select the Data Type.
If you select the Dwell Output to be Data (for example, in the lower left corner), the
DWELL version of the PPI is made for this data type.
In the example, a DWELL PPI of dBZ is generated.
6. To use the intensity filter, select Input Product Filters > Intensity.
The intensity filter allows you to eliminate any data points that are less than the Min or
greater than the Max.
A useful application is to set a Min threshold to eliminate weak echoes so that the
DWELL algorithm result shows only the strongest precipitation cores.
Check an example of the input data to determine how to best set the thresholds.
a. Enable the filter by selecting the button.
b. Type the value.
The units are for the Data Type of the input product.
In the example menu, this is dBZ.
