Optimization of the seasonal cycles of simulated CO2 flux by fitting simulated atmospheric CO2 to observed vertical profiles
the seasonal cycles CO2 flux atmospheric CO2 vertical profiles

An inverse of a combination of atmospheric transport and flux models was used to optimize the Carnegie-Ames-Stanford Approach (CASA) terrestrial ecosystem model properties such as light use efficiency...
An empirical model simulating diurnal and seasonal CO2 flux for diverse vegetation types and climate conditions
empirical model CO2 flux diverse vegetation types climate conditions
2010/1/19
We present an empirical model for the estimation of diurnal variability in net ecosystem CO2 exchange (NEE) in various biomes. The model is based on the use of a simple saturated function for photosyn...
Sensitivity of sea-to-air CO2 flux to ecosystem parameters from an adjoint model
Sensitivity sea-to-air CO2 flux ecosystem parameters adjoint model

An adjoint model is applied to examine the biophysical factors that control surface pCO2 in different ocean regions. In the tropical Atlantic and Indian Oceans, the annual cycle of pCO2 in the model i...
CO2 flux determination by closed-chamber methods can be seriously biased by inappropriate application of linear regression
CO2 flux determination closed-chamber methods linear regression
2010/1/14
Closed (non-steady state) chambers are widely used for quantifying carbon dioxide (CO2) fluxes between soils or low-stature canopies and the atmosphere. It is well recognised that covering a soil or v...
