Set the Skip Time field to 01:00 so the RAIN1 product runs every hour. This is recommended
because the RAIN1 product for multiple hour accumulations works best if there is a product
every hour.
The RAIN1 product must wait for arrival of all the input CAPPIs during the accumulation
period.
The trigger is the arrival of a CAPPI that is in the next accumulation period.
There are 2 cases that the product scheduler must handle, that is, the next hour CAPPI either
arrives or it does not arrive. Note that in the time-line figures below:
• The horizontal line represents the data time, the time of the start of a volume scan.
• The C represents an input CAPPI product.
• The vertical bar represents an the next accumulation period.
Case 1: Normal Case: Next hour CAPPI Arrives
The RAIN1 product is run as soon as a CAPPI from the next accumulation interval arrives.
Case 2: Late Case: Next accumulation Interval CAPPI Does Not Arrive
The RAIN1 product runs after the Tail and Wait times have elapsed from the file arrival
time of the last input CAPPI.
Tail is the time dierence between the data time of the last CAPPI and the next
accumulation period. The Wait time threshold is configured in IRIS Setup > Product, where
you can configure a dierent value for cases with raingage inputs. The Wait time threshold
is tuned to account for any network delays.
