Abstract The Safran–Isba–Modcou (SIM) distributed hydro‐meteorological modeling suite is developed at Météo‐France. Two ensemble forecasts were tested as input to the SIM suite. The first one was the ECMWF EPS (10‐day range, 1.5° grid, 51 members). Then, the Météo‐France PEARP (60‐h range, 0.25° grid, 11 members) was used. The methods for disaggregating the EPSs down to the 8‐km Isba grid were described. Statistical analysis of the skills of these systems (for rainfall and streamflows) was performed against observations and showed the interests of using these EPSs. The PEARP‐based streamflows showed better scores than the ECMWF ones, for low and high flows. Copyright © 2010 Royal Meteorological Society
