A new hybrid data compression algorithm for weather radar

The existent problem of the weather radar data lies in its too large data which is not conducive to its storage and transmission. This paper put forward a hybrid compression algorithm of the weather radar data that consists of three steps including pre-compression, lossy compression and lossless compression. Firstly, the paper introduced the radar data's types and characteristics, analyzing the pre-compression algorithm; Secondly, according to the practical requirements of the diverse users, it proposed the adoption of lossless compression and lossy compression algorithm for the data; Finally, the flow chart of mixed compression algorithm was presented and verified based on the actual data.
