About the FLEX Bridge Study
The FLEX Bridge Study has advanced the work of the PS Study and
PARCS projects by addressing priorities identified in these studies
and in ongoing FLEX preparatory activities. The goal was to optimize approaches for SIF retrievals
and applications in assessment of
photosynthesis & stress status in terrestrial vegetation,
including development of a calibration/validation strategy for FLEX products.
FLEX Bridge has formed a foundation for subsequent science & applications development during mission development and deployment.
The study consolidated follow-on activities leading up to the User Consultation Meeting held on 15-16 September 2015 in Krakow, Poland.
Following comprehensive assessment by ESA's Earth Science Advisory Committee, FLEX has been selected as the
Earth Explorer 8 mission.
Scientific Objectives of the Study
- To address priorities identified by previous studies and in ongoing FLEX preparatory activities.
- To optimize the fluorescence retrieval algorithm developed under the PARCS project.
- To optimize the photosynthesis retrieval model (SCOPE v1.53) and its related algorithm developed under the PS Study.
- To consolidate and develop retrievals for additional Level 2 data products.
- To further exploit applications in photoynthesis modelling & stress detection.
- To develop a calibration/validation strategy for FLEX products.
Upon absorption of a photon of light energy, chlorophyll transitions to an excited state known as
singlet chlorophyll (1Chl*), which can contribute energy either for photochemistry, heat release, or fluorescence
emission – or for the production of triplet chlorophyll (3Chl*).

About the European Space Agency...
The European Space Agency (ESA) is Europe's gateway to space, with the mission to shape the development of
Europe's space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.
ESA undertakes programmes and activities far beyond the scope of any single European country, keeping Europe
at the forefront of global space activities. Today it launches satellites for Earth observation, navigation, telecommunications
and astronomy, sends probes to the far reaches of the Solar System, and cooperates in the human exploration of space.
