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
2010/1/21
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...
Error correlation between CO2 and CO as constraint for CO2 flux inversions using satellite data
Error correlation CO2 flux inversions satellite data
2009/10/9
Inverse modeling of CO2 satellite observations to better quantify carbon surface fluxes requires a chemical transport model (CTM) to relate the fluxes to the observed column concentrations. CTM transp...
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...
The impact of diurnal variability in sea surface temperature on the central Atlantic air-sea CO2 flux
sea surface temperature central Atlantic air-sea CO2 flux
2009/3/12
The effect of diurnal variations in sea surface temperature (SST) on the air-sea flux of CO2 over the central Atlantic ocean and Mediterranean Sea (60 S–60 N, 60 W–45 E) is evaluated for 2005–2006. We...
Daily CO2 flux estimates over Europe from continuous atmospheric measurements: 1, inverse methodology
Daily CO2 flux estimates Europe inverse methodology
2009/2/19
This paper presents an inverse method for inferring trace gas fluxes at high temporal (daily) and spatial (model grid) resolution from continuous atmospheric concentration measurements. The method is ...
Systematic errors in global air-sea CO2 flux caused by temporal averaging of sea-level pressure
Systematic errors global air-sea CO2 flux temporal averaging sea-level pressure
2009/2/11
Long-term temporal averaging of meteorological data, such as wind speed and air pressure, can cause large errors in air-sea carbon flux estimates. Other researchers have already shown that time averag...
Sensitivity of sea-to-air CO2 flux to ecosystem parameters from an adjoint model
Sensitivity sea-to-air CO2 flux ecosystem parameters adjoint model
2010/1/15
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...
