SuperDARN Ionospheric Doppler Radar Velocity Measurements from 1990-1995

CEDAR Data Base at NCAR/HAO holds HF ionospheric Doppler radar data from the SuperDARN community network. Data includes line-of-sight plasma irregularity velocity and velocity spread parameters from 7 radar stations across Antarctica, Canada, Finland, and Iceland. The dataset contains campaign data collected between 1990 and 1995.

Use Cases

• Analyze temporal patterns in line-of-sight plasma irregularity velocity from specific stations like Halley or Kapuskasing.
• Correlate velocity spread measurements with geomagnetic activity indices using timestamps from campaign data.
• Map spatial variations in ionospheric plasma flow by comparing data from stations at different latitudes and longitudes.
• Validate space weather models by comparing simulated plasma velocities against observed radar data from campaigns.
• Study the climatology of ionospheric irregularities by examining multi-year campaign records from stations like Goose Bay (1988 onward).

Strengths

• Data from 7 distinct SuperDARN radar stations providing geographic diversity.
• Campaign data spans multiple years, with the longest record from Goose Bay starting in 1988.
• Includes two core physical parameters: line-of-sight plasma irregularity velocity and velocity spread.

Limitations

• Data is limited to specific campaign periods, not continuous time series.
• Row count and total data volume are unknown from the description.
• Most recent data point in the description is from 1995, making the dataset temporally stale.
