Welcome to the GEM
Inner Magnetosphere Campaign
Storms Pages

Overview:
These pages are designed to be a clearinghouse for exchange of data, plots, ideas, and analysis for the GEM Inner Magnetosphere/Storms Campaign.

Three recent storms were selected by GEM in consultation with the SHINE and CEDAR communities for intensive study. The objective of the campaign is not to analyze the storms independently but rather to intercompare the three storms. The storms were selected based on the following criteria:
* A halo CME observed by the SOHO LASCO experiment that appeared to be aimed Earthward
* A magnetic flux rope signature detected by WIND and/or ACE 3-5 days later
* A major (Dst<-100 nT) geomagnetic storm triggered
* A reasonably complete data set for the event. To meet this criteria,events were selected: (1) with as complete as possible information on the solar source regions, (2) with uninterrupted ACE and/or WIND coverage, (3) after the launch of the POLAR spacecraft to provide as complete as possible magnetospheric coverage and (4) during incoherent scatter world days.

They selected storms are:

May 1997,
September 1998, and
October 1998

In addition these pages collect information about several other storms that are not specifically part of the GEM-IM Campaign but are being actively studied by members of the community. They are:

May 1998,
March 1998,
June 1998, and
August 1998.
 

Organization of this Web Site:

You can navigate these pages by selecting a particular event or by selecting a particular data set from the menu to the left.

Each "Event Page" contains a brief description of the event and links to available data sets for that event.

Each "Data Set Page" contains a description of the summary plots and/or data sets, contact information, and links to the summary plots and data for each campaign event.

How to Add Your Data Sets:

These are community web pages. They are only as complete as you make them. If you would like to contribute any descriptions or opinions about the storms those will be included in the web pages. Likewise we would like to include links to as many relevant data sets as possible. You do not necessarily have to supply us with the data and plots. You only need to supply us with a description, contact information, and links to your data sets and/or plots. Please contact Geoff Reeves (reeves@lanl.gov) for more information.
