Real-Time Precipitation Gauge Acquisition and Quality Control

The largest known real-time, quality-controlled 1-hour precipitation gauge dataset available in the United States and Canada

MetStat® has teamed with Synoptic Data Corp to create the largest known real-time, quality controlled (QC’d) 1-hour precipitation gauge dataset available in the United States. Reliable real-time acquisition protocols coupled with a multi-sensor QC algorithm produce a high-quality 1-hour rain gauge dataset. The QC’d gauge data and statistics provide the foundation for various hydrometeorological applications, including gauge-adjusted radar-estimates, identification of gauge malfunctions, alert notifications of rainfall intensities that meet/exceed thresholds, detailed post-event analyses and climatological studies. Gauges can malfunction due to a number of different problems including freezing rain, windy conditions, gauge siting (e.g., obstructions around the gauge), under-measurement by tipping bucket gauges in high intensity rainfall, and gauge maintenance, therefore making QC an imperative step before utilizing the data. The QC system repeatedly (6x) processes data for each hour in order to capture all available real-time gauge data and leverage increasingly rich and independent datasets that have varying latencies. The complexities of gauge QC often prevent a binary (correct or not correct) decision to be made, therefore a QC confidence flag is computed for each measured value. Ranging from 0 to 1, the QC confidence flag provides an objective measure of how well the value compares to independent, multi-sensor datasets. The multi-sensor QC algorithm is based on surrounding gauges, dual-polarization QPE, radar reflectivity data, National Weather Service Stage IV gauge-adjusted radar-estimated rain data, satellite-estimated rain data and more. This system operates in the robust, redundant, and scalable Amazon Web Services cloud environment.

Data Sources

Data from nearly 25,000 stations are accessed, QC’d and archived each hour. Real-time precipitation gauge data are accessed from a variety of real-time sources, but largely from MesoWest, which aggregates weather observations from government and non-government gauge networks. Strategic alliances with other data providers allow unique and exclusive access to data sources that are otherwise difficult to attain. Pooled data from the increasing number of sources makes this the largest known real-time, QC’d rain gauge dataset available in the United States. Currently, 1-hour rain data are acquired from the following sources:
