Results of the Community Survey: "Physical Parameters to be Passed Between Models"
Physical Parameters to be passed from Solar Interior to Solar Atmosphere
Parameters:
Plasma Density
Temperature/Pressure
Velocity (vector)
Magnetic Field (vector)
Comments:
Pass time step informationLocation of transition region
- On the adjoining numerical grids (face centered or cell centered)
- Overlapping grids for gradient information and data passingProbably best thing here given state of the art is some observation-based photospheric boundary condition "data base." In particular, radial B fields given for Carrington Rotations.

Comments:
"What and Where" can be as important as "what".Interpolation of 3D data from one grid to anotherNeed to allow for possibility of 3D description of solar wind input to magnetospheric modelsDifferen variable description (i.e., cell-centered and face centered)Extensibility of variables is important for future extensions of models
