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

本研究的目的是：（1）改进和促进地磁Dst和AE的准实时推导（极光电喷流）指数在研究太阳风向磁层的能量流动中起着重要作用，（二）为深入了解日地事件的物理机制，为磁暴变化的临近预报和预报奠定基础，取得了以下成果从研究项目。改进地磁1 min值的收集;（1）与俄罗斯和美国有关机构协商改进俄罗斯AE台站的数据收集;（2）与印度当局协商促进Alibag天文台地磁数据的卫星中继。这一目标尚未实现，但通过互联网实现了数据采集。(3)我们推动了INTERGNET项目的地磁数据收集。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.促进QL地磁指数的推导：改进和促进了快速（QL）Dst和AE指数的推导。它们在我们的万维网主页上向公众开放。每月有超过10**5次访问我们的数据库。4.对地磁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.
