During the 28th orbit of Galileo in May 2000, the spacecraft imaged Jupiter's Great Red Spot (GRS) with a remarkable level of detail. Three observations of the vortex were made over a span of about two hours. We have produced mosaics of the GRS at each observation, and have measured the winds of the GRS using an automated algorithm that does not require manual cloud tracking. The advantage of using this method is the production of a high-density, regular grid of wind velocity vectors as compared to a limited number of scattered wind vectors that result from manual cloud tracking [1]. Using the wind velocity measurements, we are able to compute particle trajectories around the GRS as well as relative and absolute vorticities. We have also mapped turbulent eddies inside the chaotic central region of the GRS, similar to those tracked by Sada et al [2]. We calculate how absolute vorticity changes as a function of latitude along a trajectory around the GRS and compare these measurements to similar ones performed by Dowling and Ingersoll using Voyager imaging data [3]. Future projects with the automated cloud feature trackers will analyze Voyager images of the GRS as well as other high-resolution images of Jovian vortices. We also hope to apply this method to other relevant datasets on planetary atmospheres. References: [1] Legarreta, J. and Sanchez-Lavega, A. (2005) Icarus 174: 178--191. [2] Sada, P. et al.
