Fig. 1

A conceptual diagram of the fire object tracking system. For each half-daily time step (t), new active fire detections from VIIRS (locations and fire radiative power, FRP) are used as inputs to modify the pixel, fire and allfires objects. Subsequently the properties and geometries of every fire object are dynamically tracked across time and space, and the output data are saved in 4 layers of products (shown in different colors) with different data formats (Pickle, GeoPackage, NetCDF, and CSV, see Table 4 for detail).
