What this page should contain.

On this page it is intended that links to meetings posted here will:

• specifically identify Meetings that are of direct interest to wg4,
• also identify Meetings that are of peripheral interest to wg4,
• offer more detailed information on sessions where papers may appear that contain useful wg4 content,
• encourage attendance of meetings - not sure how this would work - where wg4 ought to appear.

Meetings with potential wg4 interest

• National Radio Science Meeting
• Boulder, Co, USA
• 4 - 7 January 2006
• European Geophysical Meeting
• Vienna, Austria
• 2-7 April, 2006
• Space Weather Week
• Boulder, Co, USA
• 25-28 April 2006
• The 2006 Space Weather Week conference will be held this spring, April 25-28, 2006, in Boulder, Colorado. This meeting will focus on the impacts of space weather and on recent scientific advances in specifying and predicting the conditions in the space environment. The conference program will highlight space weather impacts in several areas of the environment, including ionospheric disturbances, satellite drag, auroral currents, geomagnetic storms and their solar drivers, radiation belts, and solar energetic particles. We anticipate that representatives from industries impacted by space weather will attend, including those from electric power, commercial airlines, satellite operations, and navigation/communication. Space Weather Week 2006 is co-organized by the NOAA Space Environment Center, the Air Force Research Laboratory, the NSF Division of Atmospheric Science, and NASA.
