Abstract :
Considers the retrieval of cloud liquid from the brightness temperature measurements taken by a ground-based multifrequency microwave radiometer using a neural network-based inversion algorithm. Comparisons between the retrieved quantity and the atmospheric information provided by active instruments such as a 94-GHz radar and a lidar ceilometer, co-located on the RAL Chilbolton Observatory site (UK), are carried out.
