Final remarks

Foreword
Applied research serves society, its
funding is focused to solve current or
future societal challenges
To measure and understand the earth
conditions, new and improved numerical
models are leading the way, along with
improved data assimilation pipelines.
How will the Earth Observation
community better support this goal ?
“major technical challenge is the complexity of
the data and analytics procedures across
disciplines (rather than the size of the data per se)”
