Southwest Greenland Ice Sheet Yearly Ice Velocities dataset from 1984 to 2020

<p>The present dataset is published after the work of Paul Halas, J&eacute;r&eacute;mie Mouginot, Basile de Fleurian and Petra Langebroek on the Southwest of the Greenland Ice Sheet. It provides ice velocity products derived using the processing chain developped by J&eacute;r&eacute;mie Mouginot and collaborators, following the steps described in Romain Millan&rsquo;s paper &rdquo;Mapping Surface Flow Velocity of Glaciers at Regional Scale Using a Multiple Sensors Approach&rdquo; (https://doi.org/10.3390/rs11212498). In order to derive the velocity fields, we used all available imagery from Landsat 5, Landsat 7 and Landsat 8, from 1984 up to 2021, with less than 40% cloud coverage. Unfortunately, no data was collected for 1984, 1993, 1996, 1997 and 1998.&nbsp;Please also note that the spatial coverage is really limited before 1999. From 2016, satellite imagery from Sentinel-2 is also used, improving the spatial coverage of our velocity maps.<br> In this archive, we provide:<br> &bull; Complete dataset of all velocity fields derived from every image pair;<br> &bull; Yearly median results run through all data for every single pixel;<br> &bull; Yearly GeoTIFF spatial aggregate of all previously computed medians;<br> &bull; The shapefile &rdquo;cube grid.shp&rdquo; describing the grid used for our area.</p> <p>For any question, please contact Paul Halas (<a href="mailto:paul.halas@uib.no">paul.halas@uib.no</a>).</p>
