Cumulus does include some code to try to ignore some obvious rain errors. For example, if the station reports negative rain, Cumulus will normally ignore that, but if for 6 consecutive readings the rain cumulative count stays below what it was before, Cumulus will normally accept the new count as a new starting point. Because many positive values are realistic (see sub-answers), Cumulus generally will accept those as a result of accidental knocking of a tipping bucket gauge, due to wind effects on the gauge, or even due to the station electronics generating a rogue reading.
*For example, if the station reports negative rain, Cumulus will normally ignore that, but if for 6 consecutive readings the rain cumulative count stays below what it was before, Cumulus will normally accept the new count as a new starting point.
*While Cumulus is running (not when catching up with stored past values from the station log), it will ignore large increases in rainfall. (See [[#.28Invented_rain.29_Error_prevention_by_Spike_removal|below]]).
