Minimizing artifacts and biases in chamber-based measurements of soil respiration
TLDR
In this paper, the authors reviewed several recently expressed concerns about uncertainties of chamber-based measurements of CO2 emissions from soils, and explained procedures that minimize these errors and biases, and provided procedures to minimize these uncertainties and biases.About:

Assessing the eddy covariance technique for evaluating carbon dioxide exchange rates of ecosystems: past, present and future
TL;DR: The eddy covariance method is most accurate when the atmospheric conditions (wind, temperature, humidity, CO2) are steady, the underlying vegetation is homogeneous and it is situated on flat terrain for an extended distance upwind as discussed by the authors.

Nitrous oxide emissions from soils: how well do we understand the processes and their controls?
Klaus Butterbach-Bahl,Elizabeth M. Baggs,Michael Dannenmann,Ralf Kiese,Sophie Zechmeister-Boltenstern +4 more
TL;DR: Improved process understanding, building on the increased use of isotope tracing techniques and metagenomics, needs to go along with improvements in measurement techniques for N2O (and N2) emission in order to obtain robust field and laboratory datasets for different ecosystem types.

Sources of CO2 efflux from soil and review of partitioning methods
TL;DR: In this article, the root-derived CO2 efflux from soil has been distinguished and described according to their turnover rates and the mean residence time of carbon in the soil according to five main biogenic sources.

Interpreting, measuring, and modeling soil respiration
Michael G. Ryan,Beverly E. Law +1 more
TL;DR: In this article, the role of soil respiration in determining ecosystem carbon balance is discussed, and the conceptual basis for measuring and modeling soil respiology is discussed. But, the strong links between above and below-ground processes complicate using soil-respiration to understand changes in ecosystem carbon storage.

Greenhouse gas emissions from soils—A review
TL;DR: In this article, the authors reviewed soil emission studies involving the most important land-cover types and climate zones and introduced important measuring systems for soil emissions, which leads to global annual net soil emissions of ≥ 350 Pg CO 2 e (CO 2 e = CO 2 equivalents = total effect of all GHG normalized to CO 2 ).

Soil water content and temperature as independent or confounded factors controlling soil respiration in a temperate mixed hardwood forest
TL;DR: In this article, the spatial and temporal variation in soil respiration in a temperate forested landscape and to evaluate temperature and soil water functions as predictors of soil CO2 efflux was studied.

TL;DR: Data of net ecosystem carbon exchange, collected between 1996 and 1998 from 15 European forests, confirm that many European forest ecosystems act as carbon sinks and indicate that, in general, ecosystem respiration determines netcosystem carbon exchange.

Measurements of carbon sequestration by long‐term eddy covariance: methods and a critical evaluation of accuracy
TL;DR: In this paper, the turbulent exchanges of CO2 and water vapour between an aggrading deciduous forest in the north-eastern United States (Harvard Forest) and the atmosphere were measured from 1990 to 1994 using the eddy covariance technique.

Interannual extremes in the rate of rise of atmospheric carbon dioxide since 1980
TL;DR: In this article, the authors examined the changes expected from the variations in the rates of industrial CO2 emissions over this time, and also from influences of climate such as El Nino events.
