On the parallelization of atmospheric inversions of CO2 surface fluxes within a variational framework
atmospheric inversions CO2 surface fluxes variational framework
2014/12/12
The variational formulation of Bayes' theorem allows inferring CO2 sources and sinks from atmospheric concentrations at much higher time–space resolution than the ensemble or analytical approaches. Ho...
Evaluation of various observing systems for the global monitoring of CO2 surface fluxes
various observing systems the global monitoring of CO2 surface fluxes
2010/11/30
In the context of rising greenhouse gas concentrations, and the potential feedbacks between climate and the carbon cycle, there is an urgent need to monitor the exchanges of carbon between the atmosph...
Surface fluxes and tropical intraseasonal variability: a reassessment
Surface fluxes tropical intraseasonal variability
2009/12/2
The authors argue for the hypothesis that interactive feedbacks involving surface enthalpy fluxes, both turbulent and radiative, are important to the dynamics of tropical intraseasonal variability. ...
Scale-dependency of surface fluxes in an atmospheric mesoscale model:effect of spatial heterogeneity in atmospheric conditions
Scale-dependency surface fluxes atmospheric mesoscale model spatial heterogeneity
2009/11/2
We examined the nonlinear effect of spatial heterogeneity in atmospheric conditions on the simulation of surface fluxes in the mesoscale model, MM5 by testing their scale-invariance from a tower footp...
Modelling regional scale surface fluxes,meteorology and CO2 mixing ratios for the Cabauw tower in the Netherlands
regional scale surface fluxes meteorology CO2 mixing ratios Cabauw tower
2010/1/21
We simulated meteorology and atmospheric CO2 transport over the Netherlands with the mesoscale model RAMS-Leaf3 coupled to the biospheric CO2 flux model 5PM. The results were compared with meteorologi...
Influence of thermodynamic soil and vegetation parameterizations on the simulation of soil temperature states and surface fluxes by the Noah LSM over a Tibetan plateau site
thermodynamic soil soil temperature states vegetation parameterizations
2009/7/22
In this paper, we investigate the ability of the Noah Land Surface Model (LSM) to simulate temperature states in the soil profile and surface fluxes measured during a 7-day dry period at a micrometeor...
Spatial and temporal patterns of land surface fluxes from remotely sensed surface temperatures within an uncertainty modelling framework
Generalised Likelihood Uncertainty Estimation land surface fluxes surface temperatures
2009/5/18
Characterising the development of evapotranspiration through time is a difficult task, particularly when utilising remote sensing data, because retrieved information is often spatially dense, but temp...

2009/4/27
Surface fluxes are important boundary conditions for climatological modeling and Asian monsoon system. The recent availability of high-resolution, multi-band imagery from the ASTER (Advanced Space-bor...
Interdecadal Variability of the Thermohaline Circulation and High-Latitude Surface Fluxes
Interdecadal Variability Thermohaline Circulation High-Latitude Surface Fluxes
2008/12/12
An idealized North Atlantic Ocean model is forced by climatological wind stress, restoring temperature, and a diagnosed salinity flux. Both centennial and interdecadal oscillations are sustained in th...
