Solar Maximum Mission ultraviolet spectrometer data consists of photon counts in the 1170-3500 Å band. Observations from 1980 onward include images with spatial resolution as good as 1 arc sec and spectral resolution as good as 0.01 Å, designed to measure plasmas from 5000 to 200,000 K. The Solar Data Analysis Center (SDAC) archives reformatted data and provides an online database of experiments.
Use Cases
- Analyze flare evolution based on high time resolution sequences (as fast as 64 ms) mentioned in the description
- Map plasma temperature distributions in active regions based on ultraviolet wavelength scans (1170-3500 Å)
- Generate Dopplergrams of solar features based on dual-detector spectral line measurements
- Study stratospheric ozone concentration based on Earth shadow transit observations
- Build solar image sequences based on raster scanning capabilities (up to 256 arc sec square)
Strengths
- Spectral resolution as good as 0.01 Å for detailed wavelength analysis
- Spatial resolution as good as 1 arc sec for fine solar feature imaging
- Time resolution as fast as 64 ms for capturing rapid solar events
- Wavelength range spans 1170-3500 Å covering multiple ultraviolet bands
Limitations
- Last updated 1989-11-17 23:59:59.999000; freshness should be verified
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
