CCMC STEREO Support
In support of STEREO project, the CCMC is running a series of solar and heliospheric models and saving model input/output on a daily basis.

Driven by synoptic magnetogram data obtained by ground-based solar observatories, the solar coronal Luhmann Potential Field Source Surface (PFSS) model represents the approximate coronal magnetic field within 2.5 R_S.
The ENLIL solar wind is driven by the Wang-Sheeley-Arge model which extends a PFSS magnetic field to 21.5 R_S past the sonic point (where the plasma velocity starts to exceed the sound speed) using a heliospheric current sheet model and a slow and high speed solar wind distribution depending on the location of coronal holes. ENLIL covers the radial distance between 21.5 R_S and 1.6 AU in the inner heliopshere between -58 and 58 degrees heliographic latitude.
In both models, PFSS and ENLIL, the time stamp of each file refers to the end time of the solar rotation period covered by the magnetogram data. Typically this date lies about 2 days in the future as magnetic fields on the solar disc can be measured fairly reliably up to 30 degrees of heliographic longitude away from the disk center (Carrington longitude of the Earth).
