Statement

Methodology:

The vorticity estimates are determined by identifying SuperDARN velocity measurements around spatially closed loops determined by the geometry of the SuperDARN beam look directions. The vorticity at the centre of these closed loops is determined from the velocity around the loops by using Stokes' theorem.

The vorticity determination methodology is outlined in Chisham et al. (2009).

Data collection:

The analysis uses SuperDARN data from the Kodiak, Prince George, Saskatoon, Kapuskasing, Stokkseyri and Goose Bay SuperDARN radars. The raw data were analysed using the SuperDARN FitACF v2.5. The data were mapped using the Chisham et al.(2008) virtual height model. The data are presented in Altitude-Adjusted Corrected GeoMagnetic (AACGM) co-ordinates.

Data quality:

The overall quality of the vorticity estimates is highly dependent on the raw SuperDARN velocity data that provide the primary data source. These are generally of high quality with low errors. The quality of the vorticity estimates is mostly affected by missing velocity data. To mitigate this the vorticity estimates are only determined when adequate SuperDARN velocity data are available.

See Chisham et al. (2009) for full details regarding data quality.
