Abstract:
This is the fifth report to be submitted as part of the Anglian Radar Information Project. Chapter one is an introduction to the project. Chapter two discusses in detail aspects of radar systems that have a direct influence on regional precipitation estimation accuracy using weather radar data. Chapter three provides an introduction to a three phase raingauge based procedure for region wide adjustment of real time radar rainfall data. The adjustment procedure is verified and evaluated in Chapter four. Emphasis is placed on the estimation of areal rainfall amounts and the procedure is assessed for a number of individual case study rainfall events in addition to an overall assessment from all the available data. The influence of raingauge network density on radar adjustment is an important issue addressed in chapter five. The extent to which the spatial variability of the rainfall process influences areal estimation from raingauge data alone is examined for a highly spatially variable convective event and a lower spatially variable stratiform rainfall event. The findings detailed in the report are summarised and the implications discussed in the final chapter. A substantial amount of additional information pertinent to radar adjustment is contained in the twelve appendices collected at the end of the report.
