This study aims to compare at different time steps (annual, monthly, and daily) 15 rainfall estimation products (P-datasets) to 5 reference ground-based rainfall stations, over the period of 1980-1990. To classify the reliability of these products, several metrics were considered, the Kling Gupta Efficiency (KGE) and the Heidle Skills Scores (HSS at daily time step). For the study area, 5 P-datasets present high KGE values at annual and monthly time step: EWEMBI, GPCC, JRA-55 Adj, MSWEP and WFDEI-GPCC; the best 5 performing products at daily time step are CHIRPS, EWEMBI, JRA-55 Adj, MSWEP and WFDEI-GPCC. To complete this comparative analysis, it will be necessary to perform an analysis at the watershed scale and on a new temporal window. specialized PLUVIOMETRIE ETUDE COMPARATIVE PLUIE PRECIPITATION ESTIMATION METHODOLOGIE BASSIN VERSANT DJIBOUTI 062MECEAU Cudennec C. ed. edt IRD Grimaldi S. ed. edt IRD 385 59-64 2024 2199-899X Scientific Assembly of the International Association of Hydrological Sciences, 11., Montpellier (FRA), 2022/05/29-2022/06/03 https://www.documentation.ird.fr/hor/fdi:010090866 10.5194/piahs-385-59-2024 2199-899X [F B010090866] https://www.documentation.ird.fr/hor/fdi:010090866 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2024-07/010090866.pdf IRD - Base Horizon / Pleins textes 2024-06-07 2026-03-25 fdi:010090866 fre
