*************************** ** THE GEM MESSENGER ** *************************** Volume 6, Number 38 June 18, 1996 ------------------------------------------------------------------- Announcement of the Space Weather Forecast From WIND Data and IZMEM Electric Potentials ------------------------------------------------------------------- From: Volodya Papitashvili The WWW URL reference: http://www.sprl.umich.edu/space_weather/spw.html Many members of the space physics community have been using a variety of available ionospheric convection models for various purposes. The IZMIRAN Electrodynamics Model (IZMEM) is made available on-line a few months ago from the SPRL Web site (http://www.sprl.umich.edu/MIST/). This model provides useful information on geophysical conditions over both the Northern and Southern polar regions and based solely on the interplanetary magnetic field (IMF) data observed near the Earth's orbit. A new experimental "Space Weather Forecast" (SWF) model prototype was constructed recently from IZMEM for the National Space Weather Program initiative. This prototype is combined with the real-time WIND spacecraft data available on-line from the NOAA/Space Environment Center (Boulder, Colorado). The SWF prototype provides upon request a comprehensive review of geophysical conditions in the ionosphere caused by changing IMF and solar wind parameters measured by WIND spacecraft near the first Lagrangian (L1) point. Current version of the model prototype provides (1) now-cast and (2) forecast of the electric potential distributions and corresponding ionospheric convection patterns over both the Northern and Southern polar regions from real-time WIND data. Unfortunately, real-time WIND data are now available from NOAA/SEC during approximately 2 hours per day only - if current data are not available, the SWF model picks up the latest available time interval. The on-going effort in developing of the space weather forecast model prototype and its connection to other related Web sites will be reported at the forthcoming GEM Workshops (Snowmass, June 24-29, 1996). The on-line paper "Space Weather Forecast From WIND Data and IZMEM Electric Potentials" by V. O. Papitashvili, C. R. Clauer, M. L. Cooper, B. A. Belov and A. E. Levitin is posted at the GEM Snowmass'96 Online Poster Session Web site: http://www-ssc.igpp.ucla.edu/gem/snowmass96.html +-------------------------------------------------------------------------+ |To add name to the mailing list, send a message to: editor at igpp.ucla.edu | |For message to whole GEM mailing list, send to: gem at igpp.ucla.edu | | | |URL of GEM Home Page: http://igpp.ucla.edu/gem/Welcome.html | |Please update your e-mail address. | |CAUTION: Do not send messages to gem at igpp.ucla.edu unless you want | | your message to go to everyone in the GEM mailing list! | +-------------------------------------------------------------------------+
