Vegetated ecosystems largely mediate terrestrial gas and energy exchange at the atmosphere-biospherepedosphere interface. The spatial and temporal acquisition of information on vegetation status, health and photosynthetic functioning is fundamental to model the dynamic response of vegetation to changing environmental conditions, necessary for climate change and food security studies. Satellite or airborne
Earth Observation (EO) provides the opportunity to collect spatially continuous information of vegetation reflectance globally and at ecologically relevant scales. Optical EO is now advancing towards measuring a signal that is emitted by vegetation (sun-induced chlorophyll fluorescence: SIF). By flying in tandem with Sentinel-3 (S3), ESAs forthcoming FLEX mission will observe SIF, which can, in combination with reflectance, provide an indicator of actual photosynthetic activity. The FLEX-S3 multi-sensor concept
exemplifies the synergistic use of multi-source data to capture scalable ecophysiological traits. This, in combination with other Copernicus missions will allow novel data analytical techniques to be realised. Then, by combining these data with proximal sensing from drones and flux towers it becomes possible to address critical open spatiotemporal scaling questions. The synergistic use, processing and interpretation of data from multiple optical instruments at multiple scales have matured to a stage where harmonization across
Europe is now possible. This will be achieved by forming the network proposed in this Action and bringing together the Sentinel-2, S3 and FLEX passive EO communities. This Action will therefore develop and further the capabilities for the interpretation of multi-sensor and multi-scale optical measurements and develop common protocols for community use according to following Working Groups:
WG1: Closing the scaling gap: from leaf measurements to satellite images.
WG2: Closing the temporal gap: from daily observations to seasonal trends.
WG3: Realizing synergy between passive EO spectral domains.
WG4: Establishing data quality through traceability and uncertainty.
Term of the project : 4 years (2018-2020).
