The Research of Re-Calculate Technology Based on Weather Radar Data

Doppler Weather Radar has gradually been an essential tools for modern weather forecast along with the New Generation Doppler Radar Net has been completed and the deeply application in radar productions.However, New Generation Doppler Radar has still only covered any big cities due to more reasons.Particularly in western part of China, lower consistency of radar data limited the local atmospheric research and operation.Moreover, for most part of the Nation, operators cannot develop the radar product according with the local condition because of the short of radar base data.This paper combined with the Digital Graphic Processing Technique, taking the re-calculate from the radar product image, and then get the correspond radar base data with high precision.In addition, the Reflectivity Product of Hefei Weather Radar which has been made in am11:16, 9th,Aug,2007 has been applied to the Re-Calculate Platform and result the higher precision radar base data accordingly .
