WebSecond, the connected component analysis allow us to aggregate the MHWs connected in time and in space and to pass from a the grid-cell-based dataset to an event-based dataset without losing high-resolution (i.e., grid cell) information. This approach, different from the previous studies, provides the time evolution of the event at the basin scale.
