[Test Bench for Space Weather Forecast Research in NICT]
Sever "space
weather" affects on systems for our daily life (e.g., satellites
for communications and broadcasts, power system, navigation system,
and so on). Now "space weather forecasts" becomes important
for us as "Earth weather forecasts." We study space
environment and its prediction using near realtime data from ground-based
observatories and spacecraft. Our goals are quantitative predictions
using empirical models or numerical models.
International collaboration: we work as one of the Regional Warning Centers
(RWCs) of the International
Space Environment Service (ISES）.
