3.12 RAIN1: Hourly Rain Accumulation
Figure 17 RAIN1 Example Configuration
RAIN1 is hourly rainfall accumulation.
The RAIN1 product uses CAPPI or SRI data over a defined time interval, generally 60
minutes, to obtain an estimate of the rainfall that fell in that hour. The results can be
displayed or used to derive the RAINN or CATCH product.
A general-purpose volume scan task usually serves for the rainfall product. Note that the
accuracy of the rainfall product degrades with range because the beam is larger at greater
ranges. For example, the beam for a 1° beam width is 3 km across at 180 km range.
If you have a Doppler radar, select
Z as one of the task data outputs. This is corrected for
ground clutter eects.
