Observational contrains on the global atmospheric co2 budget.
Observed atmospheric concentrations of CO(2) and data on the partial pressures of CO(2) in surface ocean waters are combined to identify globally significant sources and sinks of CO(2). The atmospheric data are compared with boundary layer concentrations calculated with the transport fields generated by a general circulation model (GCM) for specified source-sink distributions. In the model the ...
متن کاملA General Circulation Model Study of Atmospheric Carbon Monoxide
The carbon monoxide cycle is studied by incorporating the known and hypothetical sources and sinks in a tracer model that uses the winds generated by a general circulation model. Photochemical production and loss terms, which depend on OH radical concentrations, are calculated in an interactive fashion. The computed global distribution and seasonal variations of CO are compared with observation...
متن کاملRegional and Global Estimation of Terrestrial CO2 Exchange from NIGEC Flux Data
of Proposed Work: We will perform a scaling analysis of terrestrial carbon exchange using several of the NIGEC flux sites in different biomes (forest, C 4 grassland, C 3 agriculture), using a numerical model of the biophysics and biogeochemistry of plants and soils (SiB2), which includes calculations of the surface fluxes of CO 2 , energy, and moisture. This model will be used to analyze local ...
متن کاملInfluence of atmospheric circulation patterns on dust transport during Harmattan Period in West Africa
This study has used TOMS AI as well as the reanalysis dataset of thirty-four years (1979-2012) to investigate the influence of atmospheric circulation on dust transport during the Harmattan period in West Africa, using Aerosol Index (AI) data, obtained from various satellite sensors. Changes in Inter-Tropical Discontinuity (ITD), Sea Surface Temperature (SST) over the Gulf of Guinea, and North ...
متن کاملThe Role of Ocean Carbon Transport in the Global Carbon Cycle
This issue addresses the present-day budget for anthropogenic CO 2 , and particularly the distribution and controlling factors of net terrestrial sinks for atmospheric CO 2 . The latter are of increasing political and economic importance under international CO2 mitigation agreements. Inverse modelling of meridional and zonal atmospheric, data(e.g. CO 2 , O 2, C), is one way to constrain terrest...
