  <dc:description>The dataset contains results of the Lagrangian Particle Dispersion Model FLEXPART as used in Schoenenberger et al. (2017).

FLEXPART was run in backward, receptor-oriented mode for 4 sites: Jungfraujoch, Monte Cimone, Mace Head, Finokalia.
FLEXPART was driven by ECMWF IFS windfields with a global resolution of 1° x 1° and 0.2° x 0.2° for the Alpine area. 50,000 particles are released every 3 hours and followed backward in time for 10 days.

Data format

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.
Binary representation of total surface footprint.
The binary files are written with R on linux and contain no stop bytes. For reading them with FORTRAN you will need to use form='unformatted' and access='direct'.
The files have the following structure:
Longitude range of grid (2 element 4 byte real)
Latitude range of grid (2 element 4 byte real)
Number of grid in longitude direction, nx (1 element 4 byte integer)
Number of grid in latitude direction, ny (1 element 4 byte integer)
Year, Month, Day, Hour, Minute of latest realease (5 element 4 byte integer)
Level top of surface layer in metres (1 element 4 byte real)
Residence times (nx x ny element 4 byte real; elements are written along longitudes first, from the largest to the smallest latitude)
