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...
متن کاملReal-time cosmic ray monitoring system for space weather
[1] We have developed a real-time system to monitor high-energy cosmic rays for use in space weather forecasting and specification. Neutron monitors and muon detectors are used for our system, making it possible to observe cosmic rays with dual energy range observations. In large solar energetic particle (SEP) events, the ground level enhancement (GLE) can provide the earliest alert for the ons...
متن کاملReal-time Weather Monitoring Using Underwater Acoustics
Acoustic rain gauges have long been espoused as a possible means of monitoring wind and rainfall in regions far from land-based measurements. The rapid provision of data from such systems could contribute to weather forecasting. This paper provides an overview of a recent equipment trial off Galway, during which wind speeds in excess of 30m s -1 were encountered. The deployment also tested the ...
متن کاملReal time monitoring for nowcasting and forecasting ionospheric space weather in Europe with ground digisondes
The Earth’s ionosphere largely determines space weather effects on radio wave communications, navigation and surveillance systems. Lately there has been an increasing demand for ionospheric nowcast and accurate forecast services by various groups of users, including European industry. The paper reviews research activities in Europe based on the exploitation of real-time ground digisondes for th...
متن کاملTime-Dependent Real-Space Renormalization Group Method
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...
