Accumulated QPF
The NBM has calibrated 6, 12, and 24-hour precipitation amounts. This means that four, 6-hour
precips do not necessarily equal the 24- hour precip for that same time period. In order to be as
accurate as possible with accumulated precipitation, we sum the largest calibrated precipitation.
Because of this, accumulated precipitation can decrease at times. An example of our summing
procedure is below.
In addition to this, don’t expect the deterministic NBM to match the NBM PQPF 50th percentile.
This is in part because each uses different data. Additionally, the deterministic NBM is tuned to
minimize MAE while PQPF data is not.
