Final remarks

The observation strategy is also designed for data assimilation and model validation purposes.

The observation strategy includes also satellite observations. In-situ or on-board measurements designed also for validation of

measurements in constrated topography areas or of new satellite missionsmeasurements in constrated topography areas or of new satellite missions (e.g. GPM/NASA)
