The quality-assured software operates as a resilient Client-Server system capable of serving hundreds of clients.ĭynamic sequence of national rain-rate images (left), catchment and location selected for Rainfall Return Period Analysis (top right), and rainfall hyetograph (bottom right) System monitoring of real-time data reception HYRAD can also pass the catchment averages through an automated interface to Flow Forecasting and Modelling Systems used in flood warning. These time-series can be displayed in total and cumulative form as a guide to flooding risk. It also forms more accurate rainfall estimates by merging radar and raingauge data, and constructs rainfall forecasts.Ĭatchment average time-series can be produced for all products. The HYRAD kernel pre-processes radar data to remove residual anomalies.

a hydrological processing kernel for improved rainfall estimation and forecasting.

real-time receipt of radar and other hydrometeorological products.

HYRAD is the standard radar display system for flood warning across England, Wales, Scotland, Northern Ireland and Belgium. Various scripts have been made available under the software directory to aid use of these data, including within GIS applications.HYRAD is an advanced weather radar display system for PCs, providing real-time receipt of radar and other hydrometeorological products, database and archiving facilities, and a hydrological processing kernel for improved rainfall estimation and forecasting. Time resolution is 5 or 15 minutes depending on the product. The 2 km data files reach to 100 km from the radar, the 5km files to 250 km.ĭetailed radar site location are given in the Met Office Weather Radar Factsheet. For example, in two severe flooding events during 1998 (at Easter over the Midlands and in late October over Wales), estimates of surface rainfall derived from radar data provided evidence of the extent and severity of the rainfall events. The value of radar-based data from the Nimrod system has been highlighted repeatedly. Single radar site data are available for 2 and 5 km Cartesian grids for various UK radar sites. Data files are available on a 1 km and 5 km Cartesian grid. Images are available for the UK as well as a further image including neighbouring European countries from 1999. The BADC holds the analyses of rainfall rate at a time resolution of 5 or 15 minutes. The main quality checking method is routine evaluation using rain gauges as ground truth.

Four or five radar scans at different elevations at each site are processed to give the best possible estimate of rainfall at the ground. The UK has a network of C-band rainfall radars and data form these are processed by the Met Office NIMROD system. This dataset has the fine-resolution analyses of rain rate for the UK and Europe. Nimrod is a fully automated system for weather analysis and nowcasting based around a network of C-band rainfall radars. These were produced by the Met Office's Nimrod system.
