There are the following "nodes" gathering data: TGO: 11 Norwegian sites FMI: 10 Finnish sites (+ 1 in Norway + 1 in Estonia) RF/Kiruna: 2 Swedish sites and SGU/Uppsala: 2 Swedish sites GFZ/Niemegk: Hornsund (via IGF/Warsaw) PGI/Apatity: Lovozero  All contributors check their own data before FMI adds them to the final database. Data are transferred to the nodes via internet or ISDN. Applications  Both events and statistical studies  Improved knowledge of the full 3-D ionospheric current system derived from combined magnetometer, radar and satellite measurements

© NERC All rights reserved European SW Networks: Issues and Prospects  Existing magnetometer networks may be a template to help develop new or more extensive ground based space weather monitoring networks.  But there are questions to be asked: Who are the data users? What do they want from magnetometer or more general space- weather networks? What is the strength (e.g. continuity) of demand for data? What is the reliability and quality of data supply? What is the maturity/adaptability of data collection and supply? What technical innovations are needed/foreseen? Higher sampling rates; novel data dissemination methods ….

© NERC All rights reserved Summary For the scientists who run magnetometer or ground based space weather networks, the possibilities for developments (scientific, technical and for applications) are probably clear. But what do the space weather data users want in detail?  This will shape how/what network scientists and technicians actually choose to do next.  For example Intermagnet would like to know if there is a user community for 1-sec data, and what format, data communications systems are needed.  Please contact Intermagnet with your ideas: Simon Flower:
