The MPE graphic shown in this section are Multisensor Precipitation Estimates, otherwise known as MPE data. The data used to produce this graphic is a combination of radar and precipitation gages. Source: Middle Atlantic River Forecast Center.

MPE rainfall

When using MPE data, it is important to remember it is vulnerable to the same inaccuracies that can be caused by either radar or precipitation gages. For radar, problems would be: freezing or frozen precipitation, low topped convection, bright banding, the reflectivity/rainfall relationship in use, calibration of the radar, radar location and elevation, range degradation, and the radar's effective coverage. For precipitation gages, problems come from freezing precipitation, windy conditions, gage siting, undermeasurement by tipping bucket gages in high intensity rainfall, and gage maintenance.

A plot map of the observed rainfall amounts for the same period as the MPE graphic has been included. Note the differences in rainfall amount between the MPE and the observed rainfall amounts. One main area extends from the Wilkes-Barre area, through Scranton and Honesdale, to the Cooperstown, Delhi and Schohaire areas. This is showing that the MPE graphic is underestimating the rainfall that fell across that area.
