Influences of observation errors in eddy flux data on inverse model parameter estimation

Description : Eddy covariance data are increasingly used to estimate parameters of ecosystem models and for proper maximum likelihood parameter estimates the error structure in the observed data has to be fully characterized. In this study we propose a method to characterize the random error of the eddy covarianc...

Carbon balance assessment of a natural steppe of southern Siberia by multiple constraint approach

Description : Steppe ecosystems represent an interesting case in which the assessment of carbon balance may be performed through a cross validation of the eddy covariance measurements against ecological inventory estimates of carbon exchanges (Ehman et al., 2002; Curtis et al., 2002).

Indeed, the widespr...

Characterizing ecosystem-atmosphere interactions from short to interannual time scales

Description : Characterizing ecosystem-atmosphere interactions in terms of carbon and water exchange on different time scales is considered a major challenge in terrestrial biogeochemical cycle research. The respective time series currently comprise an observation period of up to one decade. In this study, we exp...

Characterizing ecosystem-atmosphere interactions from short to interannual time scales

Description : Characterizing ecosystem-atmosphere interactions in terms of carbon and water exchange on different time scales is considered a major challenge in terrestrial biogeochemical cycle research. The respective time series are now partly comprising an observation period of one decade. In this study, we ex...

Does the temperature sensitivity of decomposition vary with soil organic matter quality?

Description : Knorr et al. (2005) concluded that soil organic carbon pools with longer turnover times are more sensitive to temperature. We show that this conclusion is equivocal, largely dependent on their specific selection of data and does not persist when the data set of Kätterer et al. (1998) is analysed in ...

Temperature sensitivity of decomposition in relation to soil organic matter pools: critique and outlook

Description : Knorr et al. (2005) concluded that soil organic carbon pools with longer turnover times are more sensitive to temperature. We show that this conclusion is equivocal, largely dependent on their specific selection of data and does not persist when the data set of Kätterer et al. (1998) is analysed in ...

Availability, accessibility, quality and comparability of monitoring data for European forests for use in air pollution and climate change science

Description : Data from existing monitoring programmes such as ICP Forests, ICP Integrated Monitoring and EMEP, as well as from large-scale international projects such as CarboEurope IP and NitroEurope, can be used to answer questions about the impacts of air pollution and climate change on forest ecosystems and ...
