Ground-based observations of atmospheric variables are necessary to progressively improve global climate models. Observed data can be used for model evaluation and to develop or tune process models. In arctic permafrost ...

This dataset contains time lapse pictures for the periode from 2006 to 2018, which shows the land surface in the area around the installed instruments of the related publication and datasets.

Carbon dioxide (CO2) fluxes measurd and modelled over a growing season at a (wet) polygon center and a (dry) polygon rim in the Lena River delta. The NEE fluxes were partitioned into GPP, Reco, RH, RA and NPP. Furthermore, ...

The current assessments of the carbon turnover in the Arctic tundra are subject to large uncertainties. One of the reasons is the general shortage of flux data from the vast and sparsely inhabited Arctic region. Addressing ...

Most of the world's permafrost is located in the Arctic, where its frozen organic carbon con-tent makes it a potentially important influence on the global climate system. The Arctic climate appears to be changing more ...
