What was the purpose of SIFLEX?

Hemispheric photograph of the Scots pine canopy, taken on 31 May 2002, used for estimating canopy structure parameters in the main target forest.

The main goal of the Solar Induced Fluorescence Experiment (SIFLEX) 2002 campaign was to understand whether solar-induced fluorescence measurements might someday be used to monitor and map the photochemical activity of boreal forests from space. More specifically the objectives were to:

  • measure and quantify the solar-induced fluorescence flux in the A and B oxygen absorption bands during spring thaw in a boreal forest
  • collect complementary measurements for fluorescence interpretation and radiative modelling purposes, for example spectral reflectance and solar irradiance data
  • collect a CO2 flux dataset for the study of linkage between photosynthetic activity indicators (e.g. fluorescence and PRI) and CO2.

What was the outcome of SIFLEX?

In general, SIFLEX was a highly successful experiment, because it not only demonstrated the possibility to measure fluorescence even in the case of difficult targets, but it has also provided new ideas for future developments.
