Abstract
A novel compression algorithm for weather radar data based on integer wavelet transforms and zerotree coding is presented. Considering the dependencies of the radar data, we give an efficient pre-processing of the data first. Then an advanced Embedded Zerotree Wavelet encoding algorithm is presented which uses context-based adaptive arithmetic coding to improve its performance. Experimental results show that the compression ratios are improved significantly both for lossless and lossy data compression.
