10GB of upper atmosphere data includes geophysical indices like Dst, Kp, AE, and IMF parameters, incoherent scatter radar measurements of electron densities and ion temperatures, and output from models like AMIE and TIGCM. The CEDAR database is a cooperative project managed by NCAR and HAO, sponsored by the NSF, with annual catalogues produced for community use.
Use Cases
- Analyze correlations between solar flux (10.7 cm flux) and ionospheric electron density from incoherent scatter radar data.
- Validate Thermosphere Ionosphere General Circulation Model (TIGCM) output against measured neutral winds from Fabry-Perot Interferometers.
- Study auroral electrodynamics by combining Assimilative Mapping of Ionospheric Electrodynamics (AMIE) model data with AE indices and SuperDARN radar velocity measurements.
- Investigate neutral atmosphere dynamics using neutral temperature data from IR Michelson Interferometers (OH nightglow) and line-of-sight neutral winds from middle atmosphere radars.
Strengths
- Contains approximately 10GB of diverse upper atmosphere data.
- Includes data from 11 SuperDARN HF ionospheric Doppler radars.
- Provides multiple geophysical indices (Dst, Kp, ap, AE, IMF) alongside primary instrument data.
Limitations
- Only selected data from each worldwide instrument is available, not a complete archive.
- Some data, like airglow imager data, is not in digital form (e.g., on video tape).
- Limited data available from middle atmosphere radars (MST, MF, LF, meteor wind, ST).
