The lectures will provide a background for the specific topics presented emphasizing what is still uncertain and current research lines. Each day will consist of a total of three or four lectures with an extended discussion at the presentations and at the end of the day. The workshop will be organized in three days covering the

  1. Fundamental processes of the land-atmosphere interactions,
  2. The representation of these processes in regional models and
  3. Applications of the regional simulations to real cases.

Participants are encouraged to present their research during the Poster Session that will be held during the second day of the workshop.
