Radar mosaic based on the explicit radar ray paths

Abstract

In radar observation, different ray paths, which influence the three-dimensional gridding process, is due to the different gradients of reflectivity. The earth's radius model, which could not describe the radar ray path in a certain atmospheric thermodynamic condition, is the average condition of the radar ray pathway. In order to get the mosaic data of a certain thermodynamic condition, we need an arithmetic that could produce mosaic data based on the explicit radar ray paths. In this paper, we propose a method enable us to get the mosaic data based on any certain thermodynamics profiles of atmosphere. And the results are compared to the products of radar mosaic scheme based on the fixed earth's radius model in a certain atmospheric thermodynamic condition.
