C/NOFS (Communication and Navigation Outage Forecast System) is a satellite mission dedicated to forecasting ionospheric densities, irregularities and scintillation. It will be launched early in 2005 in a 13 degrees inclination, 725 x 375 km orbit. It will have instruments that will provide plasma parameters, electric and magnetic fields (AC and DC), density fluctuations, and neutral wind. It will also have a GPS receiver, and an RF beacon. Ground-based instruments to monitor the ionosphere and the scintillation parameters are an integral part of the mission.

The purpose of this workshop was to:

• Plan specific campaigns related to C/NOFS
• Define collaborative projects that involve ground and space measurements
• Discuss the strength and limitations of the various approaches to nowcast and forecast ionospheric and scintillation parameters at low latitudes

Information on C/NOFS is available in http://www.vs.afrl.af.mil/factsheets/cnofs.html

The announcement of opportunity for a joint NASA/NSF science program related to C/NOFS and equatorial ionosphere is schedule to go out as soon as the NASA reorganization is accomplished.

Major issues that were discussed, concerning the ambient ionosphere / thermosphere, and equatorial plasma irregularities included the following:

• Role of wind shears, tides, gravity waves and E-region conductivity in the onset and damping of equatorial irregularities
• Modeling of perturbation electric field at low latitudes, and its dependence on solar wind, magnetospheric parameters, as well as ambient ionosphere
• New and innovative techniques for ionospheric and thermospheric remote measurements

The following contributions were made:
