Global Carbon Fluxes Using Multioutput Gaussian Processes Regression and MODIS Products Open
The quantification of carbon fluxes (CFs) is crucial due to their role in the global carbon cycle having a direct impact on Earth's climate. In the last years, considerable efforts have been made to scale CFs from eddy covariance (EC) data…
