| Zusammenfassung |
| Ensemble precipitation products provide an effective mechanism for quantifying the
non-linear propagation of spatially and temporally correlated retrieval uncertainties through
hydrological models. This presentation will discuss recent developments in ensemble
precipitation estimation, with an emphasis on techniques to derive ensemble rainfall fields
from multi-sensor satellite observations. It will also examine the importance of ensemble
estimation by demonstrating that incomplete representations of input uncertainty using point
error models can result in biased model outputs or calibrations. The Hydrologic
Ensemble Prediction Experiment (HEPEX) has launched a new test-bed project
to coordinate the main aspects of ensemble QPE research. The presentation will
conclude by describing the test-bed and identifying the main challenges that it faces. |
