The scarcity of observations in the Arctic has limited our understanding of the impact of covarying environmental drivers on the carbon balance of tundra ecosystems. In this study, we address some of these uncertainties through a novel record of 119 site-years of summer data from eddy covariance towers representing dominant tundra vegetation types located on continuous permafrost in the Arctic.Here we found that earlier snowmelt was associated with more net CO2 sequestration and higher gross primary productivity (GPP) only in June and July, but with lower net carbon sequestration and lower GPP in August. Although higher evapotranspiration (ET) can result in soil drying with the progression of the summer, we did not find significantly lower soil moisture with earlier snowmelt, nor evidence for a water stress that affected GPP in the peak and late growing season. Our results suggest that climate change and the associated increased length in the growing season might not benefit these northern tundra ecosystems if they are not able to continue sequestering CO2 later in the season.
