Forecasting Space Weather
Forecasting space weather events presents the ultimate challenge to a space physics model. Not only should physical constraints be satisfied, but also practical issues such as timeliness, accuracy, and reliability must be adequately addressed. To address these needs, modern space weather forecasters and users rely on a great variety of space weather models, ranging from simple regressions and e...
متن کاملCode, space and everyday life
In this paper we examine the role of code (software) in the spatial formation of collective life. Taking the view that human life and coded technology are folded into one another, we theorise space as ontogenesis. Space, we posit, is constantly being bought into being through a process of transduction – the constant making anew of a domain in reiterative and transformative practices as an incom...
متن کاملSpace Weather Effects on Communications
An overview of historical and contemporary impacts of the solar and geospace environments on communications systems. Abstract In the last century and one-half, since the invention and deployment of the first electrical communication system – the electrical telegraph, the variety of communications technologies that can be affected by natural processes occurring on the Sun and in the space enviro...
متن کاملSpace Weather Support for Communications
Ionospheric variability (space weather) significantly impacts ground and space-based communications. In essence, the electrically charged particles of the ionosphere (i.e., the partially ionized portion of the atmosphere starting at about 40 nautical miles (nm) above the Earth's surface) can attenuate, totally absorb, reflect, change direction of propagation, and change the phase and amplitude ...
متن کاملSpace Weather at 75 AU
Recent outer-heliosphere observations are reviewed from a space weather point of view by comparing the nature of solar wind, solar particle, and cosmic ray variations at the Voyagers and 1 AU. While the Sun still controls the interplanetary medium at 75 AU, the nearby boundaries of the heliosphere exert a strong influence on the environment.
