Open-air platforms have been designed to host long-term experiments lasting at least over one or two decades to decipher long-term trends and slow processes, especially in soils, but also on other terrestrial and freshwater systems. Long-term, open air experiments constitute a major scientific approach in ecosystems with potential to unravel future patterns under realistic field conditions.

AnaEE open-air platforms are exceptional in that they combine manipulation of multiple global change drivers in unique ecosystem types with advanced tools and protocols to characterize ecosystem functioning from organism to element cycles. Such platforms are critical to comprehend long-term changes in ecosystem dynamics, to detect ecological tipping points and to understand the processes determining overall ecosystem resilience to extreme events.

In AnaEE, open-air platforms can operate in different modes:
(1) as standalone experimental sites to provide physical access to plots for present-day in-depth analysis of ecosystem states
(2) as standalone experimental sites for remote access to samples and data from the past
(3) as a global network of sites to perform coordinated distributed in situ experiments, laboratory analyses of historical samples or meta-analyses of historical data
(4) as providers of long-term global change scenarios data tested against model predictions trained with independent observational data from other research infrastructures or with experimental data from enclosed AnaEE platforms.
