The Phénobs project is a Labex CEBA project. One of the central objectives of the project is to use this type of data acquired repeatedly over time to quantify variations in density and age of foliage. These variations are very difficult to measure in dense evergreen forest, and could explain the seasonal cycles of vegetation indices detected by satellite and gas exchanges with the atmosphere seen by the flow towers.
The research project aim at evidencing the putative impacts of the Spring 2020 pollution reduction on the CO2 , H2O and energy exchanges from terrestrial ecosystems with the collaborating of ICOS scientists.
The "Drought 2018" published in Philosophical Transactions Royal Society is out.
This synthesis brings together 15 articles describing and analyzing the effects of the drought that affected the north and the center of Europe in 2018.

We assembled homogenized long-term time series, up to 19 years, of measurements of net ecosystem exchange of CO2 (NEE) and its partitioning between gross primary production (GPP) and respiration (Reco) for five different ecosystems representing the main plant functional types (PFTs) in France. Part of these data was analyzed to determine the influence of the main environmental variables on carbon fluxes between temperate ecosystems and the atmosphere, and to investigate the temporal patterns of their variations. A multi-temporal statistical analysis of the time series was conducted using random forest (RF) and wavelet coherence approaches.
