Space Weather Studies Using Low-frequency Interplanetary Scintillation Observations
نویسندگان
چکیده
Plasma disturbances originating on the Sun, such as coronal mass ejections (CMEs), are a major factor in determining ‘space weather’ in the near-Earth environment. Virtually the only current source of routine observations of these disturbances as they propagate through the interplanetary medium are interplanetary scintillation (IPS) data. We review current work on time-dependent tomographic reconstructions of the heliospheric density and velocity based on currently available IPS remote sensing observations. We discuss the importance of the tomographic analysis of IPS data for an effective space weather forecast system, in particular in connection with the future Low Frequency Array (LOFAR) instrumentation.

Space weather capabilities of low frequency radio arrays
Radio arrays currently operating below 1 GHz have observed interplanetary scintillations of radio sources to derive valuable information on the density and velocity of the solar wind and coronal mass ejections. New large radio arrays are currently in the design and development phase, and are characterized by wide fields of view, high sensitivity, and multiple beam capabilities. One such array, ...

The Low Frequency array (LOFAR) will be a next generation digital aperture synthesis radio telescope covering the frequency range from 10 to 240MHz. The instrument will feature full polarisation and multi-beaming capability, and is currently in its design phase. This work highlights the solar, heliospheric and space weather applications where LOFAR, with its unique and unprecedented capabilitie...
متن کاملTracking heliospheric disturbances by interplanetary scintillation
Coronal mass ejections are known as a solar cause of significant geospace disturbances, and a fuller elucidation of their physical properties and propagation dynamics is needed for space weather predictions. The scintillation of cosmic radio sources caused by turbulence in the solar wind (interplanetary scintillation; IPS) serves as an effective ground-based method for monitoring disturbances i...
متن کاملThe Dynamic Spectrum of Interplanetary Scintillation: First Solar Wind Observations on LOFAR
The LOw Frequency ARray (LOFAR) is a next-generation radio telescope which uses thousands of stationary dipoles to observe celestial phenomena. These dipoles are grouped in various ‘stations’ which are centred on the Netherlands with additional ‘stations’ across Europe. The telescope is designed to operate at frequencies from 10 to 240MHz with very large fractional bandwidths (25-100%). Several...
متن کاملThree-dimensional exploration of the solar wind using observations of interplanetary scintillation
The solar wind, a supersonic plasma flow continuously emanating from the Sun, governs the space environment in a vast region extending to the boundary of the heliosphere (∼100 AU). Precise understanding of the solar wind is of importance not only because it will satisfy scientific interest in an enigmatic astrophysical phenomenon, but because it has broad impacts on relevant fields. Interplanet...
