Automatic retrieval of plasmaspheric electron densities: First results form Automatic Whistler Detector and Analyzer Network

There is an increasing `demand' for plasmaspheric electron density data for plasmasphere models in Space Weather related investigations, particularly in modeling charged particle accelerations and losses in Radiation Belts. The global Automatic Whistler Detector and Analyzer (AWDA) system network detects millions of whistlers in a year. But the analysis of the whistlers to extract the plasmaspheric electron density information has thus far proved to be slow and time consuming. A recently developed whistler inversion model opened the way for an automated process of whistler analysis, not only for single whistler events but for complex analysis of multiple-path propagation whistler groups. An automatic analyzer algorithm was also developed and a practical implementation of such a system on a PC cluster is done. The prototype of AWDA runs on the cluster in quasi-realtime mode, the analysis of a whistler group take a few minutes. In this paper we present the first results of test runs processing whistlers from our archive database. We are planning to install this algorithm on AWDANet nodes in the near future to archive the quasi-realtime mode of operation in providing plasmaspheric electron densities.
