UCL Geography in vegetation fluorescence study

European Space Agency Paris Workshop

UCL Geography in vegetation fluorescence study

Professor Philip Lewis, Dr Mat Disney and NERC PhD student Jacques Malaprade attended the European Space Agency (ESA) 5th International Workshop on Remote Sensing of Vegetation Fluorescence, in Paris on 22-24 April.

Fluorescence in vegetation is a by-product of photosynthesis, and measuring it on large scales using aircraft and satellites has been gaining a lot of interest in recent years. Fluorescence seems to be a very close indicator of vegetation productivity at a given time, and responds very strongly to plant stress, such as in drought conditions.

Recent work (e.g. Guanter et al., 2012) has shown that we may be able to exploit a range of new and forthcoming satellite missions to monitor fluorescence from space. Following their earlier work, UCL colleagues will work with ESA teams exploring the possibility of launching a new satellite aimed at measuring fluorescence.

Jacques' PhD research meanwhile focuses on how this new signal can be modelled to understand and exploit it more effectively. At the Workshop he was able to meet other researchers working in the same area, and discuss developments in modelling.
