  "description": "<p>The dataset contains results of the Lagrangian Particle Dispersion Model FLEXPART as used in Schoenenberger et al. (2017).</p>\n\n<p>FLEXPART was run in backward, receptor-oriented mode for 4 sites: Jungfraujoch, Monte Cimone, Mace Head, Finokalia.<br>\nFLEXPART was driven by ECMWF IFS windfields with a global resolution of 1&deg; x 1&deg; and 0.2&deg; x 0.2&deg; for the Alpine area. 50,000 particles are released every 3 hours and followed backward in time for 10 days.</p>\n\n<p><strong>Data format</strong></p>\n\n<p>Each sub-folder for each site contains individual footprint files for the main and nested output domain of FLEXPART. Individual files are provided for every 3 hour interval and follow a custom binary format.<br>\nBinary representation of total surface footprint.<br>\nThe binary files are written with R on linux and contain no stop bytes. For reading them with FORTRAN you will need to use form=&#39;unformatted&#39; and access=&#39;direct&#39;.<br>\nThe files have the following structure:<br>\nLongitude range of grid (2 element 4 byte real)<br>\nLatitude range of grid (2 element 4 byte real)<br>\nNumber of grid in longitude direction, nx (1 element 4 byte integer)<br>\nNumber of grid in latitude direction, ny (1 element 4 byte integer)<br>\nYear, Month, Day, Hour, Minute of latest realease (5 element 4 byte integer)<br>\nLevel top of surface layer in metres (1 element 4 byte real)<br>\nResidence times (nx x ny element 4 byte real; elements are written along longitudes first, from the largest to the smallest latitude)</p>\n\n<p>&nbsp;</p>\n\n<p>Schoenenberger, F., S.
