Since 1990, in order to provide a snow cover evolution model with hourly relevant meteorological parameters, the software SAFRAN has been developped by Météo-France (CEN).

In this presentation, we will describe the goals to reach, the methods used, and the evaluation of the results in different zones ( French Alps, Pyrenean chain, Iceland, ...)

We focus our attention on several points like :

- nearest neighbours research

- precipitation module

- operationnal constraints

- ...
