    dc:description "The same detection + overlap-tracking algorithm run locally outside Galaxy (scikit-image + scipy), used to confirm the Galaxy result and to provide a hermetic, credential-free reproduction." .

    dc:description "The CellProfiler object-tracking pipeline (IdentifyPrimaryObjects + MeasureObjectSizeShape + TrackObjects) segments and tracks dividing cell nuclei in fluorescence time-lapse microscopy, applied to the IVT fields through a Galaxy workflow. It is a cross-discipline transfer of a bioimaging tracker to Earth-system science. Atmospheric rivers are identified using the established Guan & Waliser (2015) criteria (IVT threshold, length, length/width ratio, poleward flux)." .

      "Recovery of coherent atmospheric-river objects per timestep — each with a persistent identity, centroid trajectory, length, IVT intensity and poleward flux — and whether the tracker follows them across time as they intensify, drift, merge and split." .

      "Gridded fields of integrated water-vapour transport (IVT) from the ERA5 reanalysis (here the North Pacific, early February 2017, 6-hourly, 0.25 degrees), in which atmospheric rivers appear as long narrow filaments of high IVT." .
