[Depfis] Reunion sobre prediccion de Space Weather en Naciones Unidas

[sergio]

Hola,

Reenvio información acerca de un meeting sobre mejoras en predicción de 
Space Weather, a realizarse en una sede de Naciones Unidas, Viena, Austria.

Saludos.

: Title of the Meeting:
: "Expert Meeting on Improving Space Weather Forecasting in the Next Decade"
:
: To be held in conjunction with the 51st session of the Scientific and
: Technical Subcommittee of the Committee on the Peaceful Uses of Outer
: Space (COPUOS)
:
: Dates: 10-11 February 2014, Co-incident with the first two days of
: the Scientific and Technical Subcommittee (STSC) of the Committee
: on the Peaceful Uses of Outer Space (COPUOS)
:
: Location: The United Nations, Vienna International Center, Vienna,
: Austria (Room number to be announced later.)

:
: The International Space Weather Initiative (ISWI), with the support
: of the United Nations Committee for the Peaceful Uses of Outer Space,
: has been very active in promoting the installation of new ground-based
: instrumentation in non-traditional locations. In particular, there
: has been substantial progress in the observation of the equatorial
: ionosphere, solar transients, and energetic particles from space.
: In the coming decade these observations will become available in
: real time and will be an important new data source for the forecasting
: of space weather events. New instruments are either in the process
: of deployment, or planned over the next decade. Similarly, the
: International Living with a Star (ILWS) program has been very active
: coordinating the plans of the world’s space agencies in the
: planning of new space missions, and in the development of space
: weather modeling and forecasting.
:
: Space weather is inherently an international enterprise. Solar and
: magnetic storms can affect large regions of the Earth simultaneously,
: and equatorial ionospheric disturbances occur routinely around the
: globe. It is therefore appropriate to promote improvement in space
: weather forecasting for the benefit of all nations.  The purpose of
: this meeting is to bring together international scientists currently
: working in space weather research to discuss the paths for improvement
: of space weather forecasting during the next decade. Current
: forecasts are useful, but have limited accuracy.
:
: New space missions and ground based instrumentation will ultimately
: provide data which will substantially improve space weather
: predictions. Examples include broad arrays of ground based instruments,
: sub-L1 missions employing solar sail technology or special deep space
: orbits to maintain position between the Sun and Earth could increase
: the current warning time for interplanetary disturbances by up to
: a factor of ten. New missions with spacecraft stationed at L5, on
: the far side of the Sun, or over the pole of the Sun have also
: been suggested.
:
: The vulnerabilities of global navigation satellite systems (GNSS)
: are well categorized, and it is understood that space weather is the
: largest contributor to single-frequency GNSS errors. Primary space
: weather effects on GNSS include range errors and loss of signal reception.
: The GNSS industry faces several scientific and engineering challenges
: to keep pace with increasingly complex user needs: developing receivers
: that are resistant to scintillation and improving the prediction of
: the state of the ionosphere. With GNSS modernization, the use of
: additional signals is expected to reduce errors caused by the ionosphere.
:
: Contributions for this meeting are solicited as both oral and poster
: presentations that identify new and innovative missions, instruments,
: and theoretical developments that point to new observational information
: required to improve our basic forecasting capability or accuracy during
: the next decade. Priority for oral presentation will be given to
: contributions suggesting new instrumentation, ground or space based,
: new mission concepts, and theoretical contributions which suggest new
: observations needed to improve current space weather forecasting.
: Participation is open to all and broad international participation
: is anticipated. Presentations will be made available online in
: electronic format subsequent to the meeting, and the results of the
: meeting will be summarized in a brief report.
:
: The agenda will feature an introductory and overview session with
: very general talks about space weather, followed by a session on
: the current state of forecasting, sessions on Ground Based
: instrumentation including GNSS, and sessions on new observational
: concepts for space missions that will provide new data for space
: weather forecasting in the future.
