Abstract: For more than 20 years, the CEN (Snow Study Centre) has been developing operational software for snow data analysis including models for avalanche hazard forecast. “Poste Nivologie” is now the daily working station of the “departmental” avalanche forecasters of Météo-France. All nivo-meteorological data (observations and forecast information) can be processed and displayed in various windows in order to help avalanche forecasters in snow cover analysis. All data of existent years can be accessed on line (since 1970 for many stations). • This new application has been developed by the computing division of CEN. It is integrated in the new computing architecture of the Departmental Centres of Météo-France, based under client / server technology, Oracle database and Windows OS (WS2003-XP). • Many recent tools have been used to improve it : Oriented Object Analysis method, Software Configuration Management, Object Programmation, COM / DCOM, … • All developments have been done under a project structure named DOLMEN (“Développement OpérationneL des Moyens d’Expertise Nivologique”) where all the actors of nivology in Météo-France were involved, from management committee to final users. This application has been deployed for the autumn 2002 in the 11 Departmental Centres of Météo- France in charge of operational avalanche forecast. After several upgrades over two years, a major evolution was done in December, 2005, in order to integrate many innovations including the modeling chain Safran-Crocus-Mepra. New versions are yet planned until 2008 to access climatological data, to merge observations and forecasting, to produce commercial data and to connect “Poste Nivologie” to local application GELINIV.
