The Solar Ultraviolet Measurements of Emitted Radiation (SUMER) instrument is a UV telescope and spectrometer on the ESA/NASA SOHO spacecraft. SUMER has observed the Sun from approximately 1.5 million kilometers since 1996, delivering data on plasma flows, temperatures, and magnetic activity in the solar atmosphere. The data are archived at the Max-Planck-Institut für Aeronomie and mirrored at several international institutions.
Use Cases
- Analyze plasma flow characteristics and turbulence based on Doppler shift measurements
- Determine plasma densities and temperatures based on extreme ultraviolet line intensities
- Investigate structures associated with solar magnetic activity based on high-resolution EUV images
- Study wave motions in the solar atmosphere based on spectral line profiles and broadenings
Strengths
- Data collection began in 1996, providing a long-term observational record
- Instrument provides high spatial, temporal, and spectral resolution in the EUV range
- Observations cover a wide temperature range from 10,000 to 2,000,000 Kelvin
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Last update date is unknown; freshness unverified
