Abstract
An inversion technique based on neural networks is used to retrieve profiles of cloud liquid from ground-based multifrequency data acquired by a radiometer at the RAL Chilbolton Observatory site. The effectiveness of the approach has been assessed by comparing the retrieved liquid density with both the reflectivity factor measured by a co-located 94 GHz radar and the backscattering coefficient measured by a lidar ceilometer. The Doppler capability of the radar has been exploited to discriminate between cloud liquid, rain and ice.
