Characterization of rainfall variability across scales

The high variability of rainfall across scale, which is a basic feature that should be taken into account in all other aspects (radar rainfall estimation, merging techniques, nowcasting), was studied in a multifractal framework. Initial suggestions to overcome some limitations were made. This was developed by partners from ENPC. Additional information:
