Jupiter horizontal wind velocities at cloud level from Cassini David J. Armstrong (7751312) Roland M. B. Young (24810517) Andrew J. Lancaster (24810529) Turbulence, Jupiter (Planet) Jupiter (Planet) -- Atmosphere Image processing Migrated from ePrints This dataset contains horizontal wind velocity vectors at the top of Jupiter’s main cloud deck, covering four rotation periods during December 2000. These wind measurements are based on a series of visible camera images taken by NASA’s Cassini spacecraft. They were analysed using a cloud tracking procedure based on a Correlation Imaging Velocimetry (CIV) method developed to analyse fluid dynamics experiments. The dataset contains 1123505 horizontal wind velocity vectors covering 360 degrees in longitude and +/-50 degrees in planetocentric latitude. The dataset also includes a Python script to convert the velocity vectors from spherical geometry to oblate spheroidal geometry, and to estimate observational uncertainties.<br><br>Data record consists of 2 data files, in .py and .nc format, and a readme file. The dataset is documented in readme.pdf. The data file is in uncompressed netCDF format. Raw images were taken by the Cassini spacecraft, operated by NASA / JPL-Caltech / Cassini Imaging Team / Space Science Institute. Processed images produced by Ashwin R. Vasavada and Carolyn Porco, available from http://pds-atmospheres.nmsu.edu/Jupiter/CassiniMaps.txt. Velocity fields were computed using UVMAT/CIV (LEGI, Grenoble), available from http://servforge.legi.grenoble-inp.fr/projects/soft-uvmat, and described by Galperin et al. (2014), Icarus, 229, 295-320, doi:10.1016/j.icarus.2013.08.030. 2017-01-01T00:00:00Z Dataset Dataset 10.82444/warw.33802558.v1 https://figshare.com/articles/dataset/Jupiter_horizontal_wind_velocities_at_cloud_level_from_Cassini/33802558 CC BY 4.0
