For stations which supply a rain rate, Cumulus uses that. For stations which don't supply a rain rate (e.g. Fine Offset and La Crosse), Cumulus simply takes the rain total from the last five minutes and calculates a rate based on that; e.g. a single tip of 0.3mm in 5 minutes is a rate of 3.6mm/hr. When data from the station's logger is used, a similar calculation is performed, but the interval used is the logger interval rather than five minutes. | For stations which supply a rain rate, Cumulus uses that.
