Statement

Methodology:

The vorticity estimates are determined by taking SuperDARN line-of-sight velocity measurements of the ionospheric plasma flow 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 by summing the flow velocity around the loops, and dividing by the area, using Stokes' theorem. The ionospheric vorticity determination methodology is outlined in detail in Chisham et al. (2009).

Data collection:

The data set comprises vorticity estimates from the following overlapping pairs of SuperDARN radars: (1) Kodiak (a) and Prince George (b); (2) Saskatoon (t) and Kapuskasing (k); (3) Stokkseyri (w) and Goose Bay (g); (4) Finland (f) and Pykkvibaer (e). The raw data were analysed using the SuperDARN FitACF v2.5. The data were geolocation mapped using the Chisham et al. (2008) virtual height model. The vorticity locations are presented in both geographic and 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 around the closed loops. To mitigate this, the vorticity estimates are only determined when adequate SuperDARN velocity data covering all sides of the closed loop are available. See Chisham et al. (2009) for full details regarding data quality.
