What Can CoCoRaHS Data Do?

Here's an example of the sort of detailed precipitation mapping that is made possible by networks like CoCoRaHS.  The following images show 24-hour Rainfall ending around 9am Saturday, September 29th 2012.  Radar estimates are readjusted based on ground truth from CoCoRaHS and other observers.  These so-called "Ground Truth" reports help improve radar rainfall algorithims and can teach forecasters under what circumstances (atmospheric conditions) the rainfall estimates work well, and when they don't.  This in turn improves forecasts of flash flooding.

(Note: Not every observation is labelled on the maps, but if you sent in precip data for Saturday morning, rest assured, it is in the analysis).

We hope to create these maps daily in the near future, and we'll re-create past maps for Monsoon Season 2012.
