Topics ● ● ● About the Community Coordinated Modeling Center (CCMC) Earth's magnetosphere model runs Perspecta visualization

The Community Coordinated Modeling Center ● ● ● Dedicated to space weather research & analysis, development of models Combination of resources from NASA and other gov’t. orgs. Based in GSFC

Space Weather ● ● ● Comes from solar activity Mixture of radiation and plasma Affects us on Earth

Space Weather: Magnetosphere ● ● Earth has a magnetosphere Current theory – magnetic field generated by rotation of molten core

Space Weather: Magnetosphere ● ● Theoretically looks like dipole Crushed and pulled by solar wind

Space Weather: Magnetosphere ● ● Actuality – looks similar to comet Constantly shielding Earth from harmful effects

The Community Coordinated Modeling Center ● ● Provides services for researchers Runs on Request, and many others

The Community Coordinated Modeling Center ● ● Runs on Request – free service Other models besides magnetosphere

The Community Coordinated Modeling Center ● ● Model run of magnetosphere Simulation of solar wind velocity Solar wind velocity increase from 0 Gradual increase in magnetic field

Visualization Say Hello. . .

Visualization ● Converted flat images to 3 D. vrml files

Visualization ● ● Results much easier to understand Clip shows magnetosphere forming

Visualization ● ● Converted again to frames for Perspecta display Data can be viewed in true 3 D, any angle, no glasses needed

Visualization
