Short summary
Clyde River (CLY) SuperDARN radar velocities reflecting plasma flows in the ionosphere are consistent with measurements by the incoherent scatter radar RISR. While agreement is good in the range of RISR velocity magnitudes of 0–700 m s−1, CLY velocities become progressively smaller at faster flows. In one example of strong disagreements between the instruments, by 200 m s−1, the radars monitored strongly sheared flows. Validation of the CLY radar confirms the reliability of SuperDARN operation.
