The Congress urged Members to make every effort to prevent the deterioration of climate-relevant data and to make these data available to support climate change analyses and relevant climate services. In the framework of operational and scientific research actions around the updating of hydrological standards in West Africa (Actualisation des Normes hydrologiques en Afrique de l'Ouest - ActNAO Project) and in response to the WMO call, we used the NUNIEAU software (NUmérisation de NIveaux d'EAU en mer ou en rivières - free software from CEREMA) which allows the digitization of different types of paper documents by automatic recognition. This software has been used on rainfall pluviograms in Burkina Faso and Côte d'Ivoire. The use of this tool allows rainfall analysis on intraday time steps, a time step that is very useful for the knowledge and management of flash-flood events in small basins, especially urban basins. Illustrated by a few scientific results, access to these data, which remains very limited in West Africa, opens up fields of analysis that are not only disciplinary but also, and above all, inter or transdisciplinary. specialized CLIMATOLOGIE TRAITEMENT DE DONNEES PLUVIOMETRIE LOGICIEL PRECIPITATION CRUE GESTION METHODOLOGIE BASSIN VERSANT NUNIEAU LOGICIEL CHANGEMENT CLIMATIQUE VALORISATION BURKINA FASO COTE D'IVOIRE 021CLIMAT01 062MECEAU02 122LOGIC Cudennec C. ed. edt IRD Grimaldi S. ed. edt IRD 385 219-224 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:010090867 10.5194/piahs-385-219-2024 2199-899X [F B010090867] https://www.documentation.ird.fr/hor/fdi:010090867 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2024-07/010090867.pdf IRD - Base Horizon / Pleins textes 2024-06-07 2026-03-25 fdi:010090867 fre
