INCREASE infrastructures (EU 7th FP) provide access for visiting scientists to study the effects of long-term climate manipulation treatments in field experiments on shrubland ecosystems across Europe. Climate manipulations include prolonged drought and warming treatments which have lasted for over 10 years, and free-air increased CO2 treatment in Denmark, Brandbjerg running over 5 years. Non-invasive measurement techniques are particularly encouraged for minimizing the disturbance on experimental plots. We visited the experimental sites in Italy (Porto Conte) and Denmark (Mols and Brandbjerg) in summer 2011 to conduct reflectance measurements in visible and short-wave infrared spectral region (400-2500 nm).
