Abstract

Summary form only given. An analysis was made of time-series data from the S-band CP-2 radar and the C-band DFVLR radar from which radar parameters such as Z_DR propagation differential phase shift, φ_DP, and cross-correlation are derived. Model simulations were used to study the relationship between these radar quantities and rainfall rate for gamma raindrop size distributions. At C-band the backscatter differential phase shift cannot be ignored, so algorithms to separate out this component from φ_DP were derived. Absolute attenuation (absorption) at C-band cannot be neglected when φ_DP is large. A scheme whereby the absolute attenuation could be estimated using φ_DP (after backscatter phase shift effects have been removed) was developed.
