 ### Storm Detection and Tracking
 
-Storm tracks are determined and stored using the [stormTracking](https://github.com/ecjoliver/stormTracking) [2] algorithm by Eric Oliver.  This code automatically detects and tracks atmospheric storms (cyclones) and high-pressure centers (anticyclones) using a series of surface pressure maps. While the initial code used NCEP data, it is easily adapted to use ERA5 data and resolution.

While the initial code used NCEP data, it is easily adapted to use ERA5 data and resolution.  A sample storm track dataset (`storm_track_slp.npz`) is provided for testing `stormviz` following the steps to run the tool.
