CEDAR Data Base holds outputs from several large-scale atmospheric models, including the Thermosphere Ionosphere General Circulation Model and the Assimilative Mapping of Ionospheric Electrodynamics procedure. The collection includes specific runs for dates like 22 March 1979, generic runs for winds and tides, and outputs for specific longitudinal points. These models were developed by researchers at NCAR/HAO, including Raymond Noble, Arthur Richmond, Jeffrey Forbes, and Maura Hagan.
Use Cases
- Analyze neutral winds, temperatures, and tidal motions from TIGCM generic runs to study atmospheric coupling.
- Use AMIE procedure outputs for auroral energy flux and electric potential to model ionospheric electrodynamics.
- Compare solar and lunar semi-diurnal tide calculations from different models to validate tidal forcing mechanisms.
- Study the height of integrated conductances and currents at 100 km from AMIE for specific event periods.
Strengths
- Includes outputs from multiple established models like TIGCM and AMIE.
- Contains specific model runs for a defined date (22 March 1979) and location (70W).
- Covers a vertical atmospheric range from approximately 97 km to 550 km.
Limitations
- Exact row counts, file sizes, and total volume of data are unknown.
- Temporal coverage appears limited to specific runs rather than a continuous time series.
- Geographic coverage for some model runs is restricted to a single longitude.
