IDRA: IRCTR Drizzle Radar

Little is known on the impact of the increase in anthropogenic aerosols on the global climate. It can potentially have a cooling effect via the second indirect aerosol effect which is poorly understood because of the lack of sound measurements. A radar devoted to the observation of the spatial distribution of drizzle, in combination with other sensors, would certainly give a better insight to this phenomenon. IRCTR is currently developing such radar, which will be placed in Cabauw (The Netherlands) a meteorological site that will provide synergy with other instruments. This paper describes the requirements, the system design and the products obtained.
