Earth Observation data are unique snapshots of the condition of the Earth at a specific point in time. As such they constitute a humankind asset, which needs to be preserved, i.e. safeguarded against loss and kept accessible and usable for current and future generations. This task becomes more important in the view of over 40 years’ worth of data available in Earth Observation archives around the world – and the increasing demand for monitoring long-term variations environmental parameters, such as sea surface temperature or global ozone distributions, which require long time series of data. Moreover, with the advent of new, high resolution Earth Observation missions and programs, data volumes are expected to grow significantly over the next years.
