| Zusammenfassung |
| Improving systematic observations of land cover, as an Essential Climate
Variable, should contribute to a better understanding of the global climate
system and thus improve our ability to predict climatic change. The aim of
this paper is to bring global land cover observations closer to meeting the
needs of climate science. First, consultation mechanisms were established
with the climate modeling community to identify its specific requirements in
terms of satellite-based global land cover products. This assessment
highlighted specific needs in terms of land cover characterization, accuracy
of products, as well as stability and consistency needs that are currently
not met or even addressed. The current land cover representation and mapping
techniques were then called into question to specifically focus on the
critical need of stable products expressed by climate users. Decoupling the
stable and dynamic components of the land cover characterization and using a
multi-year dataset were proposed as two key approaches to allow generating
consistent suites of global land cover products over time. |
