CEDAR Storm Study Workshop

The CEDAR Storm Study is a cooperative effort among scientists in the U.S.A. and overseas in the in study of scientific ionosphere/thermosphere storm intervals with particularly good data coverage. The aim is to involve interested scientists with F-region/thermosphere data or modeling capabilities in coordinated efforts to understand the coupled upper atmospheric regions at different heights and on a global scale during geomagnetically disturbed conditions, in line with the objectives of the NSF CEDAR initiative.

The current Storm Study covers a total of 8 ionosphere/thermosphere storm intervals.

• March 20-21, 1990
• June 11-12, 1991
• November 2-11, 1993
• May 1-5, 1995
• Jan 6-10, 1997
• April 10-11, 1997
• September 23-27, 1998
• October 18-24, 1998

The September and October storms were added to the study after the 1999 CEDAR meeting. Additional information about the CEDAR Storm Study, including on-going projects, can be found at:

This workshop will provide an opportunity for participants to give brief progress reports on their ongoing projects and identify new and interesting projects. In addition to the science studies, a portion of the workshop will be devoted to charting the future of the CEDAR Storm Study, including the planning of the 3 day CEDAR Storm Study workshop at Millstone Hill.

Our workshop in Boulder provides an opportunity for all those interested in ionosphere/thermosphere storms to hear results of the latest research, discuss progress on the various projects, and identify new coordinated studies. As time permits, collaborators on individual projects will be able meet in small groups to plan the next stages in their joint efforts.

The specific agenda for the workshop is:

• Introduction - R. Sitar
  
• CEDAR Storm Study Planning - R. Sitar
  
• Reports:
  
  • G. Crowley - Transformation of Ionospheric Patches into Blobs on the Nightside
