The biogeochemical dynamics of carbon in the ocean is a subject of fundamental interest to environmental studies. In this context, we have implemented a ten year run of the Brazilian Earth System Coup...
Regional-scale geostatistical inverse modeling of North American CO2 fluxes: a synthetic data study
Regional-scale geostatistical North American CO2 fluxes a synthetic data study

In order to examine energy partitioning and CO2 exchange over a steppe prairie in Inner Mongolia, China, fluxes of moisture, heat and CO2 in the surface layer from June 2007 through June 2008 were cal...
Estimating surface CO2 fluxes from space-borne CO2 dry air mole fraction observations using an ensemble Kalman Filter

We have developed an ensemble Kalman Filter (EnKF) to estimate 8-day regional surface fluxes of CO2 from space-borne CO2 dry-air mole fraction observations (XCO2) and evaluate the approach using a ser...
On using radon-222 and CO2 to calculate regional-scale CO2 fluxes
radon-222 CO2 regional-scale CO2
