Quasi-real time derivation of geomagnetic AE and Dst indices and forecasting of geomagnetic storm variations

本课题研究的目的是：(1)改进和促进在太阳风向磁层能量流研究中起重要作用的地磁Dst和AE（极光电喷流）指标的准实时推导；(2)深入了解太阳地球事件的物理性质，为地磁风暴变化的临近预报和预报奠定基础。从这个研究项目中，我们得到了以下结果：地磁1 min值采集的改进(1)与俄罗斯和美国的相关组织进行了谈判，以改进俄罗斯AE站的数据收集。(2)与印度当局进行了谈判，以促进Alibag天文台地磁数据的卫星中继。虽然目前还没有实现，但是通过Internet实现了数据采集。(3)推进INTERMAGNET项目地磁数据采集工作。2 .地磁数据库建设：加快地磁1秒值和1分钟值数据库建设。推进QL地磁指数的推导：改进和促进了QL Dst和AE指数的推导。它们在我们的WWW主页上向公众开放。我们的数据库每月被访问的次数超过10**5次。人们对地磁风暴及其探测进行了若干研究。

The purpose of this research project are (1) to improve and to promote quasi-real time derivation of the geomagnetic Dst and AE(Auroral Electrojet) indices which play important roles in studies of energy flow to the magnetosphere from the solar wind, (2) to obtain deeper insight to physics of solar terrestrial events and to make foundation of nowcasting and forecasting geomagnetic storm variations.We have obtained the following results from the research project.1. Improvement of collection of geomagnetic 1 min values;(1) We negotiated with related organizations in Russia and the United States to improve data collection from the Russian AE stations,(2) Negotiation was also made with Indian authorities to promote satellite relay of geomagnetic data from Alibag observatory. It has not been achieved yet but, instead, data acquisition through Internet was realized.(3) We promoted geomagnetic data collection by the INTERMAGNET project.2. Construction of geomagnetic databases : We accelerated database construction of geomagnetic 1 sec values and 1 min values.3. Promotion of derivation of QL geomagnetic indices : Derivation of the quick-look (QL) Dst and AE indices has been improved and promoted. They are open to public on our WWW home page. More than 10**5 accesses per month has been observed to our databases.4. Several studies have been made on geomagnetic storms and detection of them.
