PROBLEM TO BE SOLVED: To derive a micro physical quantity of cloud particles comprising a cloud by remove sensing. SOLUTION: This cloud micro physical quantity deriving system determines the ice water volume and the effective radius of the ice particle in the layer by calculating a set of an ice water volume an effective radius of the ice particle satisfying one observation value from observation data of a cloud radar and a rider according to each layer having the cloud, and by finding those coincidence with the other observation value among them. This system also performs attenuation correction of the calculated cloud layer by deriving the radar observation data and the rader observation data of an upper layer, and repeats the attenuation correction of the 1+1st data by deriving the ice water volume and the effective radius of the ice particles in the i-th (i=1, 2, etc.), cloud layer from the first detected cloud layer to the cloud crest.
