Soil quality is threatened by the increase in human population and by the fact that most of
the cultivable land is intensively used. The initial interest in this topic focused on defining soil …

Temperate and boreal forest ecosystems contain a large part of the carbon stored on land, in
the form of both biomass and soil organic matter. Increasing atmospheric [CO2], increasing …

Net ecosystem exchange (NEE) of CO2 between the atmosphere and forest ecosystems is
determined by gross primary production (GPP) of vegetation and ecosystem respiration …

Within the past decade, several global land cover data sets derived from satellite
observations have become available to the scientific community. They offer valuable …

There is a growing consensus that land surface models (LSMs) that simulate terrestrial
biosphere exchanges of matter and energy must be better constrained with data to quantify …

Using data from 28 flux measurement sites, we performed an analysis of the relationship
between annual net ecosystem exchange (NEE) and the length of the carbon uptake period …

Over two-thirds of terrestrial carbon is stored belowground and a significant amount of
atmospheric CO 2 is respired by roots and microbes in soils. For this analysis, soil …

Process‐based models can be classified into:(a) terrestrial biogeochemical models (TBMs),
which simulate fluxes of carbon, water and nitrogen coupled within terrestrial ecosystems …

Although more than 80% of carbon dioxide emissions originate in urban areas, the role of
human settlements in the biosphere evolution and in global carbon cycling remains largely …

At Tharandt/Germany eddy covariance (EC) measurements of carbon dioxide and heat
fluxes are performed above an old spruce forest since 1996. The last ten years cover almost …
