Monitoring the Sun: A Global Space Weather Enterprise

Space Weather and Real-Time Monitoring

Recent advance of information and communications technology enables to collect a large amount of ground-based and space-based observation data in real-time. The real-time data realize nowcast of space weather. This paper reports a history of space weather by the International Space Environment Service (ISES) in association with the International Geophysical Year (IGY) and importance of real-tim...

Modeling a space weather event from the Sun to the Earth: CME generation and interplanetary propagation

[1] We present a three-dimensional (3-D) numerical ideal magnetohydrodynamics (MHD) model describing the time-dependent expulsion of a coronal mass ejection (CME) from the solar corona propagating to 1 astronomical unit (AU). The simulations are performed using the Block Adaptive Tree Solar-Wind Roe Upwind Scheme (BATS-R-US) code. We begin by developing a global steady-state model of the corona...

The utility of polarized heliospheric imaging for space weather monitoring

A polarizing heliospheric imager is a critical next generation tool for space weather monitoring and prediction. Heliospheric imagers can track coronal mass ejections (CMEs) as they cross the solar system, using sunlight scattered by electrons in the CME. This tracking has been demonstrated to improve the forecasting of impact probability and arrival time for Earth-directed CMEs. Polarized imag...

Space Weather Forecast Predicts Changes in Sun-Earth Space Environment by Using Observation Data

Space Weather Effects Detected by Gps Based Tec Monitoring

The world-wide use of GPS satellites for navigation and positioning offers the unique chance for permanent monitoring the total electron content (TEC) of the ionosphere on global scale. Based on the analysis of GPS-derived TEC maps computed at DLR/DFD Neustrelitz for the European area on a routine base with a time resolution of 10 min the paper demonstrates the power of this new tool to detect ...
