The precipitation estimates provided herein are derived from the NWS WSR-88D Doppler Radar. Radar preciptiation estimates can be grossly inaccurate, so radar-based precipitation values are calibrated with the routinely available hourly surface gages. The combined product provides the spatial resolution of radar with the increased accuracy of surface gage networks. These gage-calibrated radar estimates are known as Multi-sensor Precipitation Estimates, or MPE.

There are still errors in MPE. A study by the State Climate Office of North Carolina suggests that MPE compares well with an independent daily precipitation gage network over the Carolinas. Details of this study are available online.

The MPE grids used in this tool are routinely produced by the National Weather Service and National Centers for Environmental Prediction.
Mapping Application

MAP

This simple mapping application enables you to visually see accumulated MPE estimates over time. When zoomed in, roads, water features, and town names can be overlayed for reference. Additionally, your project sites can be noted on the map for additional reference. The past 6, 12, 24, 48, and 72 hours are available to view spatially. 1-week, 30- and 90-day options are also available.

Cardinal

Cardinal Data Request System

Cardinal is a high-powered, user-oriented, one-stop-shop for North Carolina weather and climate data housed at the North Carolina State Climate Office. Cardinal makes weather and climate data more accessible to users, with features and prompts that take the guesswork out of station and parameter identification and selection. The system includes a step-by-step interface to request data, as well as a My Requests page for users to access their requested data and to view their current, in-progress, recently completed, and past data requests.
