Research Interests
I am involved in several of the numerical models that are developed by the institute, both developing the models, using them and managing their operational deployments. These models include the multi-layer, energy balance snow model SNOWPACK, the Alpine surface processes model Alpine3D and the meteorological input/output preprocessing library MeteoIO. I also do my own research using these models (see the publications list).
Models
Most of the models that are developed in our group are available under an Open Source license on our software forge, at https://models.slf.ch. However, we request you to register in order to get access to these models. Here are some links related to these models:
