摘要

Monitoring of the Earth's and Sun's environment is an essential task for the now-and forecasting of Space Weather and the modelling of interactions between the Sun and the Earth. Such interaction originates from the pressure of the solar wind, the related magnetic field changes, the hot plasma and highly energetic particle streams generated by the active Sun. A large amount of charged particles emerging from the Sun interacts thereby with the magnetic field of the Earth, enters directly or via reconnection into the Earth's magnetosphere and is captured then partly within the radiation belts.Due to the asymmetry and complexity of the magnetic field structure, the involved particle environment and its dynamics, it is necessary to capture the state of the magnetic field and the particle distribution in a sufficiently large number of sampling points around the Earth, such that it allows state-monitoring and modelling of the involved processes with sufficient accuracy and timeliness. Further information of such interactions can be derived by observation of the involved processes via remote sensing (e.g. auroral imaging) or probing of the ionospheric properties as a function of the altitude and position around Earth.Within the Space Situational Awareness programme, ESA is implementing a space weather monitoring system, which is also making use of hosted payloads as part of the establishment of a Distributed Space Weather Sensor System (D3S). Two hosted payloads are currently being implemented on two missions: a versatile magnetometer on the Korean Geo-Kompsat-2A satellite and a radiation monitor hosted on EDRS-C. We will give an overview of the Space Situational Awareness (SSA) Enhanced Space Weather Monitoring System, the currently planned D3S and its hosted payloads, and we will report on the related constraints on possible flight opportunities for operational Space Weather Monitoring.
