Sensitivity of simulated CO2 concentration to regridding of global fossil fuel CO2 emissions
fossil fuel CO2 emissions
2014/12/19
Errors in the specification or utilization of fossil fuel CO2 emissions within carbon budget or atmospheric CO2 inverse studies can alias the estimation of biospheric and oceanic carbon exchange. A ke...
Modelling of light driven CO2 concentration gradient and photosynthetic carbon assimilation flux distribution at the chloroplast level
photosynthesis chloroplast CO2 flux Calvin cycle limiting factors
2012/5/3
The steady state of the two-substance model of light driven carbon turnover for the photosynthetic CO2 assimilation rate is presented. The model is based on the nonlinear diffusion equation for a sing...
An efficient method for measuring CO2 concentration in gassy lakes: Application to Lakes Nyos and Monoun, Cameroon
Lake Nyos Lake Monoun in-situ analysis dissolved CO2 gas self-lifting
2017/8/9
A simple and efficient method for measuring CO2 concentration of deep water of gassy lakes is proposed. This method is based on the gas self-lifting in a plastic hose that is deployed into deep water ...
Technical Note: A new coupled system for global-to-regional downscaling of CO2 concentration estimation
A new coupled system global-to-regional CO2 concentration estimation
2010/8/12
We introduce a global-to-regional nesting scheme for atmospheric transport models used in simulating concentrations of green house gases from globally distributed surface fluxes. The coupled system of...
Ecosystem effects of CO2 concentration：evidence from past climates
Ecosystem effects past climates CO2 concentration
2009/12/3
Atmospheric CO2 concentration has varied from minima of 170–200 ppm in glacials to maxima of 280–300 ppm in the recent interglacials. Photosynthesis by C3 plants is highly sensitive to CO2 concentrat...
The sensitivity of stand-scale photosynthesis and transpiration to changes in atmospheric CO2 concentration and climate
atmospheric CO2 transpiration
2009/3/25
The 3-dimensional forest model MAESTRO was used to simulate daily and annual photosynthesis and transpiration fluxes of forest stands and the sensitivity of these fluxes to potential changes in atmosp...
Modeling atmospheric CO2 concentration profiles and fluxes above sloping terrain at a boreal site
atmospheric CO2 concentration profiles sloping terrain
2008/12/31
CO2 fluxes and concentrations were simulated in the planetary boundary layer above subarctic hilly terrain using a three dimensional model. The model solves the transport equations in the local scale...
Technical Note: Long-term memory effect in the atmospheric CO2 concentration at Mauna Loa
atmospheric CO2 Mauna Loa
2008/12/1
The monthly mean values of the atmospheric carbon dioxide concentration derived from in-situ air samples collected at Mauna Loa Observatory, Hawaii, USA during 1958–2004 (the longest continuous recor...
Dynamics of the terrestrial biosphere, climate and atmospheric CO2 concentration during interglacials: a comparison between Eemian and Holocene
terrestrial biosphere climate atmospheric CO2 Eemian Holocene
2008/11/11
A complex earth system model (atmosphere and ocean general circulation models, ocean biogeochemistry and terrestrial biosphere) was used to perform transient simulations of two interglacial sections (...
The effect of seawater CO2 concentration on growth of a natural phytoplankton assemblage in a controlled mesocosm experiment
seawater CO2 concentration natural phytoplankton assemblage controlled mesocosm experiment
2014/5/4
We examine the effects of seawater pCO2 concentration of 25, 41, and 76 kPa (250, 400, and 750 matm) on the growth rate of a natural assemblage of mixed phytoplankton obtained from a carefully control...
Testing the effect of CO2 concentration on the dynamics of marine heterotrophic bacterioplankton
CO2 concentration marine heterotrophic bacterioplankton
2014/4/23
To date no study exists that directly addresses changes in dynamics of heterotrophic bacteria in surface waters
in relation to partial pressure of CO2
(pCO2
). Therefore, we studied the effect of c...
