The 3 GHz CAMRa is the largest fully steerable meteorological radar in the world. The large antenna of the 3 GHz weather radar gives it an extremely narrow beam, only 0.25 degrees wide, resulting in an increased resolution (at 100km from the dish, the resolution of an 0.25 degree beam is 0.4km). It has dual-polarisation capability, which means that it can transmit and receive both horizontally and vertically polarised pulses.This makes it possible to determine the shape and orientation of cloud and precipitation particles in the atmosphere.
It also has full 'Doppler' capability, which means it can map the radial component of a wind field.
Copernicus, the 35 GHz (9 mm wavelength) cloud radar is a fully coherent, Ka band, dual-polarisation, pulse compression Doppler radar. It is currently installed on a ground fixed pedestal with a 2.4 m parabolic antenna. The radar is designed to complement the 94 GHz (3 mm) "Galileo" cloud radar currently operating at the Observatory for observations of cloud microphysics and climatology.
