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 of the FLEX Bridge Study was to optimize approaches for SIF retrievals and applications in the assessment of photosynthesis and stress status in terrestrial vegetation, including the development of a calibration/validation strategy for FLEX products.

Scientific objectives of the study were:

  • 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 and stress detection.
  • To develop a calibration/validation strategy for FLEX products.

A key finding in our previous work is the inherent value of having both the red and the far-red fluorescence emission peaks for applications.  This underscores the unique advantages of FLEX and its FLORIS sensor which will be optimized to extract these spectral features with appropriate spatial and spectral detail.

FLEX Bridge will form the foundation of subsequent science & applications development during mission development and deployment.

FLEX Bridge Study Project Meetings

Three official FLEX Bridge meetings were held as part of this study:
    – The Kick-off meeting (KO) was held on 03 October 2014.
    – A milestone progress meeting (PM-1) was held on 19 February 2015.
    – The final presentation & review (FR) was held on 08 December 2015.
In addition, various telecons were held throughout the project as needed.
