5th International Workshop on Remote Sensing of Vegetation Fluorescence
22 - 24 April 2014, Paris, France
Remote sensing of vegetation fluorescence is considered a promising technique for large scale monitoring of photosynthetic activity. Since emitted fluorescence is directly linked to primary production and thus to carbon assimilation by terrestrial ecosystems, measurements of solar-induced fluorescence could be used as an early indicator of the health and vitality of vegetation.
Routine observations of sun-induced fluorescence from space would advance our knowledge of biosphere dynamics and help improve our understanding of the terrestrial component of the carbon cycle, reducing uncertainties in the forecasting of global climate changes.
Since the first Workshop on Remote Sensing of Solar Induced Vegetation Fluorescence, held in ESA-ESTEC, Noordwijk, the Netherlands, in June 2002, much progress has been made in addressing some of the key issues that were identified at the workshop: instrument development, field data acquisition, models of leaf and canopy fluorescence, fluorescence retrieval, atmospheric corrections and space mission design. The second workshop, hosted by the Canadian Space Agency in Montreal (Quebec), Canada, in November 2004, represented a consolidation in the vegetation fluorescence community's interest in proposing the FLEX (FLuorescence EXplorer) mission in response to ESA's Call for Earth Explorer Ideas in 2005. A first proposal for the FLEX mission was considered by ESA as a candidate mission for the Earth Explorer 7 Core Mission program, but was not selected for the next phase.
The 3rd Workshop in February 2007 in Italy, and the 4th in November 2011 in Valencia, Spain , were oriented towards the preparatory activities of a replacement FLEX mission and the consolidation of methods and techniques for fluorescence use and acquisition. Shortly thereafter, ESA selected the revised FLEX proposal for phase A/B1 concept development as one of two formulation candidates for the Earth Explorer 8 mission.
This 5th Workshop on Remote Sensing of Vegetation Fluorescence, which will held in Paris, France in April 2014, will address the current status of research and understanding of vegetation fluorescence, within the framework of the upcoming selection by ESA of the Earth Explorer 8 mission to go forward in the next mission phase. This workshop will be an opportunity among various scientific communities to discuss and communicate about new advances in the FLEX mission preparatory activities, as well as generic topics related to vegetation fluorescence and its applications. Among the focus topics to be addressed: instrument development; methods for fluorescence retrieval; techniques for signal analysis; ground and airborne measurement campaigns; fluorescence models at leaf, canopy and TOA levels; model inversions; relationships between fluorescence, physiology, canopy structure and CO2 assimilation; and fluorescence applications in environment monitoring.
