The BASS 2000 project archives and disseminates solar ground-based observations from French instruments. Data includes raw spectral data and images from THEMIS, global radio flux and radioheliographs from Nancay, Hydrogen-alpha and Calcium-II spectroheliograph images from Meudon, and Hydrogen-alpha coronographs from Pic du Midi Observatory. The project is funded by the national 'Sun-Earth relationship Program', the Midi-Pyrenees Observatory, and the Astrophysic Laboratory of Toulouse.
Use Cases
- Analyze solar magnetic field extrapolations based on simulation data mentioned in the description
- Study solar activity cycles based on synoptic maps from Meudon spectroheliographs
- Model solar radio emissions based on global radio flux and radioheliograph data from Nancay
- Compare ground-based observations with space-based data as the database is complementary to MEDOC (SOHO and TRACE data)
Strengths
- Data is sourced from multiple established solar observation instruments, including THEMIS, Meudon spectroheliograph, and the Nancay Radioheliograph.
- The database is designed for long-term safe-keeping and is complementary to other solar databases like MEDOC.
- The project includes objectives for standardization and pedagogical tool development in solar physics.
Limitations
- Row count and dataset size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
