Validation of the CUTLASS HF radar gravity wave observing capability using EISCAT CP-1 data
International audience Quasi-periodic fluctuations in the returned ground-scatter power from the SuperDARN HF radars have been linked to the passage of medium-scale gravity waves. We have applied a technique that extracts the first radar range returns from the F-region to study the spatial extent an...
