Comparative temporal analysis of CO2 flows between 5 French stations of the ICOS Ecosystem network

Written by ca no comments

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.

ICOS study shows clear reduction in urban CO2 emissions as a result of Covid-19 lockdown

Written by ca no comments

Integrated Carbon Observation System, ICOS, is the first to release results of a scientific study that shows a large reduction in carbon dioxide (CO2) emissions in seven European cities during the lockdown caused by the Covid-19 virus. The study is conducted by ICOS ecosystem scientists together with colleagues around Europe.
