![]() This provides complementary rainfall information to the operational UK Met Office radar measurements. In addition, since the radar is located within London and closer to the ground, it can provide more accurate rainfall estimates with higher spatial resolution (street level) for this urban area. ![]() Because of this, X?Band radars are more sensitive and can detect smaller particles, such as drizzle, snow and the tiny water particles associated to cloud development. X-Band radars operate on wavelengths between 2.5 and 5 cm, which are smaller than those at which the C-Band Met Office radars operate (between 4 and 8 cm). It will be used for detecting drizzle during the upcoming Wimbledon Tennis Championship, as well as for improving methodologies for modelling and forecasting of urban pluvial flooding.Īs part of the Interreg RainGain project (coordinated by Prof Cedo Maksimovic and Dr Christian Onof), the Urban Water Research Group of Imperial College London has installed a portable X Band RS90 “Rainscanner” weather radar, supplied by radar manufacturer Selex, on the rooftop of a high building in London for a period of 6 months from April to September 2013. It can detect smaller particles, such as snow and drizzle, and can provide more accurate rainfall estimates with higher spatial and temporal resolution. The new (X-Band) radar is more sensitive than (C-Band) radars currently used by the Met Office.
