Selected breakpoints of net forest carbon uptake at four eddy-covariance sites
Tellus: Series B, Chemical and Physical Meteorology, 2021 Extensive studies are available that analyse time series of carbon dioxide and water flux measurements of FLUXNET sites over many years and link these results to climate change such as changes in atmospheric carbon dioxide concentration, air temperature ...

Frontiers in Plant Science, 2022 Seagrass meadows are one of the most productive ecosystems on the planet, but their photosynthesis rate may be limited by carbon dioxide but mitigated by exploiting the high concentration of bicarbonate in the ocean using different active processes ...

Carbon Dioxide Uptake by Hydrated Lime Aerosol Particles [PDF]
Aerosol Science and Technology, 2004 The reaction of the greenhouse gas, CO2, with Ca(OH)2 was explored using single-particle Raman spectroscopy to track the chemical reaction. Single particles were levitated in an electrodynamic balance (EDB) to maintain the particle in a laser beam. The levitation voltage provided gravimetric data. The humidity in the EDB chamber was varied to determine

Towards a universal model for carbon dioxide uptake by plants [PDF]
Nature Plants, 2017 Gross primary production (GPP)-the uptake of carbon dioxide (CO2) by leaves, and its conversion to sugars by photosynthesis-is the basis for life on land. Earth System Models (ESMs) incorporating the interactions of land ecosystems and climate are used to predict the future of the terrestrial sink for anthropogenic CO21 .

The lifetime of excess atmospheric carbon dioxide [PDF]
, 1994 We explore the effects of a changing terrestrial biosphere on the atmospheric residence time of CO2 using three simple ocean carbon cycle models and a model of global terrestrial carbon cycling.

Combining tower mixing ratio and community model data to estimate regional-scale net ecosystem carbon exchange by boundary layer inversion over 4 flux towers in the U.S.A. [PDF]
, 2011 We evaluated an idealized boundary layer (BL) model with simple parameterizations using vertical transport information from community model outputs (NCAR/NCEP Reanalysis and ECMWF Interim Analysis) to estimate regional-scale net CO2 fluxes from 2002 to ...

The ocean carbon sink – impacts, vulnerabilities and challenges [PDF]
, 2014 Carbon dioxide (CO2) is, next to water vapour, considered to be the most important natural greenhouse gas on Earth. Rapidly rising atmospheric CO2 concentrations caused by human actions such as fossil fuel burning, land-use change or cement production ...

Chemical Engineering Transactions, 2018 Comparative adsorption of methane and carbon dioxide on activated carbon and ZIF-8 (Zeolitic Imidazolate Framework) at 35 °C and up to 100 psi was made.

An observing system simulation for Southern Ocean carbon dioxide uptake [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 The Southern Ocean is critically important to the oceanic uptake of anthropogenic CO 2 . Up to half of the excess CO 2 currently in the ocean entered through the Southern Ocean. That uptake helps to maintain the global carbon balance and buffers transient climate change from fossil fuel ...
