Data: High Rain Rate
The High Rain Rate is the amount of rain that would fall in one hour if the rain rate as calculated below continued for the full hour.
The rain rate is calculated by measuring the time interval between each rainfall increment. When there is rainfall within the archive period, the highest measured value is reported. When no rainfall occurs, the rain rate will slowly decay based on the elapse time since the last measured rainfall.
The West Juneau Weather Station uses a 5 minute archive period.
