Observing earth critical zone processes in the bayelva basin (CZO@Bayelva) The dataset includes CO2 fluxes measurements during summer period in different area along the transect from CCT to Ny-Alesund airport. The measures are performed using a portable accumulation chamber in dark (Ecosystem respiration, ER) and light (Net Ecosystem Exchange) condition. For each plot, about 20 measures are performed, including soil temperature and volumetric soil water content. CO2/H2O daily average values and standard deviation. Each measurement day contains a number of half-hour measurements.

Observing earth critical zone processes in the bayelva basin (CZO@Bayelva) Data represents the average values and the corresponding standard deviation obtained from each plots at different site along the transect CCT-airport. Each average value is obtained as a mean over a set of more than 20 point measures for each plot and each sampling date. Flux data are complemented by measurements of soil temperature and volumetric water content. data obtain using accumulation chamber and portable probe.
