| Zusammenfassung |
Cross-track ion drifts measured by the DMSP satellites are compared with
line-of-sight SuperDARN HF velocities in approximately the same directions.
Good overall agreement is found for a data set comprising of 209 satellite
passes over the field of view of nine SuperDARN radars in both the Northern
and Southern Hemispheres. The slope of the best linear fit line relating the
SuperDARN and DMSP velocities is of the order of 0.7 with a tendency for
SuperDARN velocities to be smaller. The agreement implies that the satellite
and radar data can be merged into a common set provided that spatial and
temporal variations of the velocity as measured by both instruments are
smooth.
