The real time range-time plot above shows the most recent two hours of data from the selected radar and beam for range gates 0 - 75. 15 radars out of the 35+ have real time capabilities, including all 5 of SuperDARN Canada's radars. On occasion, internet connection and real time links can fail, and at those times the real time plots will be unavailable for the radar experiencing issues.

Plasma drift velocity along the beam direction. Blue shows plasma moving towards the radar and red shows plasma moving away from the radar. Ground scatter can be detected using the SNR and spectral width and is colored grey. Measured in meters per second.
Ratio of the radar echo power (signal) to that of the atmospheric noise measured in decibels.
Larger spectral width usually indicates more perturbed plasma. However a very small spectral width may indicate reflection of the radar beam from the ground. Measured in meters per second.
The angle at which the returning radar echo is approaching the radar above the horizon. Measured in degrees.
Daily overview plots of the above parameters can be found here. These summary plots are made once the data files are processed and as such may take a few days to appear on the website. The data files themselves can be found here for SuperDARN Canada managed radars. See our Data Info page for more information regarding other institutions data policies and access.
