The data/insitu_flux directory contains the in-situ CO2 flux measurements in Excel format. The data/modeling directory contains artifacts from modeling. The data/products directory contains products resulting from the analysis (predicted CO2 concentrations and estimated CO2 fluxes throughout Denmark) in csv format.
