  abstract = {{The CEFLES2 campaign during the Carbo Europe Regional Experiment
Strategy was designed to provide simultaneous airborne measurements of
solar induced fluorescence and CO$_{2}$ fluxes. It was combined
with extensive ground-based quantification of leaf- and canopy-level
processes in support of ESA's Candidate Earth Explorer Mission of the
``Fluorescence Explorer'' (FLEX). The aim of this campaign was to test if
fluorescence signal detected from an airborne platform can be used to
improve estimates of plant mediated exchange on the mesoscale. Canopy
fluorescence was quantified from four airborne platforms using a
combination of novel sensors: (i) the prototype airborne sensor AirFLEX
quantified fluorescence in the oxygen A and B bands, (ii) a
hyperspectral spectrometer (ASD) measured reflectance along transects
during 12 day courses, (iii) spatially high resolution georeferenced
hyperspectral data cubes containing the whole optical spectrum and the
thermal region were gathered with an AHS sensor, and (iv) the first
employment of the high performance imaging spectrometer HYPER delivered
spatially explicit and multi-temporal transects across the whole region.
During three measurement periods in April, June and September 2007
structural, functional and radiometric characteristics of more than 20
different vegetation types in the Les Landes region, Southwest France,
were extensively characterized on the ground. The campaign concept
focussed especially on quantifying plant mediated exchange processes
(photosynthetic electron transport, CO$_{2}$ uptake,
evapotranspiration) and fluorescence emission. The comparison between
passive sun-induced fluorescence and active laser-induced fluorescence
was performed on a corn canopy in the daily cycle and under desiccation
stress. Both techniques show good agreement in detecting stress induced
fluorescence change at the 760 nm band. On the large scale, airborne and
ground-level measurements of fluorescence were compared on several
vegetation types supporting the scaling of this novel remote sensing
signal. The multi-scale design of the four airborne radiometric
measurements along with extensive ground activities fosters a nested
approach to quantify photosynthetic efficiency and gross primary
productivity (GPP) from passive fluorescence.
