In this article, the term '''rogue value''' is used for when in Cumulus you see a value that you believe should not be there. Generally, it refers to a single data point, but where that weather derivative is cumuluative in nature it might affect a string of recorded values. Regardless of whether it is single or not, such a rogue value can be progated into several of the extreme derivatives that Cumulus calculates and maintains in its various logging files.

Here are a typical examples:
* it might appear that a gust of 89 mph was recorded as the highest on a day when you are sure it was not that windy, a single data point is wrong
* it might appear that a gust of 89 mph was recorded as the highest on a day when you are sure it was not that windy, a single data point is wrong
* perhaps you saw 478.8mm of rain occurring on a dry day, this might be a single data point error, or as rain total is cumuluative a series of wrong date points

* an extreme can be attributed to wrong time (or even wrong day), because the time on your weather station clock is wrong
