Physico-chemical parameters measured at a high spatial resolution in the Miellajokka catchment, Sweden

High spatial resolution dataset of CO2 evasion in a stream network in northern Sweden (52.5 km2; Miellajokka catchment). We measured key hydrological parameters to estimate k600, directly determined the pCO2, and estimated stream CO2 evasion across 168 sites in the stream network. Comparison of pCO2 values from a global compilation of river chemistry (GLORICH; Hartmann et al., 2014) with calculated site-specific k600 and CO2 evasion.
