Rainfall forecast data generated at the Met Office is vital for providing weather and flood warnings. This project looked at ways of improving the accuracy and reliability of the radar network as well as fully exploiting and bringing into operation the latest technology. Radar is particularly important in detecting localised rainfall (often not detected or under-sampled by rain gauge networks), especially where it falls on catchments prone to flash flooding.

The upgrade to the UK’s dual polarisation radar network in 2016 and the updated data analysis methods from this study means that we can make a step change in the accuracy of rainfall estimates. We can do this in particular in very intense
