The team

A multidisciplinary team contributes to the development and validation of the SAFYE-CO2 model and AgriCarbon-EO processing chain. Our team covers a wide range of expertise, essential for the devellopment of complex tools. Our expertise include agronomy, hydrology, remote sensing, numerical methods, scientific computing, and field observation systems. We cherish this diversity as it is the backbone for sucess.

Previous contributors

The devellopment of the AgriCarbon-EO and SAFYE-CO2 current tools has span from earlier research activities that paved the way, like the works of  Dr. Amanda Veloso and Gaétan Pique who published with the team the first reports and papers SAFYE-CO2. More earlier studies on the SAFYE model from Benoit Duchemin, Martin Claverie, and Marjorie Battude, though they used a different approach and didn't include carbon budget, have also paved the way for the current advancements.  

A strong link with the field observatory

The devellopement of the SAFYE-CO2 and AgriCarbon-EO tools requires an intensive ammount of data for the calibration and validation (cal/val). So, without a dedicated team for the regional observatory (OSR: Observatoire Spatiale Regional) and the EIS (Environmental Information System) at CESBIO supported by the INSU and the University Toulouse III, the calibration and validation of the tools would have not beed possible. We thank thus the colleagues from the OSR (Tiphaine Tallec, Franck Granouillac ,Aurore Brut, Valérie Demarez, Hervé Gibrin , Bartosz Zawilski...) for their continuous contribution to the validation and calibration datasets.  Similarly, we extend these thanks to all the colleagues and partners that shard valuable data with the team.
