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...
Supersaturation calculation in large eddy simulation models for prediction of the droplet number concentration
Supersaturation calculation large eddy simulation models droplet number concentration
2014/12/10
A new parameterization scheme is described for calculation of supersaturation in LES models that specifically aims at the simulation of cloud condensation nuclei (CCN) activation and prediction of the...

Modeling wet deposition concentration inorganics over Northeast Asia MRI-PM/c
2014/12/10
We conducted a regional-scale simulation over Northeast Asia for the year 2006 using an aerosol chemical transport model, with time-varying lateral and upper boundary concentrations of gaseous species...
Meteorological and trace gas factors affecting the number concentration of atmospheric Aitken (Dp = 50 nm) particles in the continental boundary layer: parameterization using a multivariate mixed effects model
Meteorological number concentration atmospheric Aitken particles continental boundary layer multivariate mixed effects model
2014/12/9
Measurements of aerosol size distribution and different gas and meteorological parameters, made in three polluted sites in Central and Southern Europe: Po Valley, Italy, Melpitz and Hohenpeissenberg i...
Effect of carbonate ion concentration and irradiance on calcification in planktonic foraminifera
carbonate ion concentration and irradiance calcification planktonic foraminifera
2010/1/21
The effect of carbonate ion concentration ([CO32−]) on calcification rates estimated from shell size and weight was investigated in the planktonic foraminifera Orbulina universa and Globigerinoi...
Antarctic summer sea ice concentration and extent:comparison of ODEN 2006 ship observations,satellite passive microwave and NIC sea ice charts
summer sea ice concentration ODEN 2006 ship observations satellite passive microwave NIC sea ice charts
2010/2/3
Antarctic sea ice cover has shown a slight increase (<1%/decade) in overall observed ice extent as derived from satellite mapping from 1979 to 2008, contrary to the decline observed in the Arctic regi...
Relationships between the surface concentration of particulate organic carbon and optical properties in the eastern South Pacific and eastern Atlantic Oceans
surface concentration particulate organic carbon optical properties eastern South Pacific
2010/1/15
We have examined several approaches for estimating the surface concentration of particulate organic carbon, POC, from optical measurements of spectral remote-sensing reflectance, Rrs(λ), using field d...
Temperature response of soil respiration is dependent on concentration of readily decomposable C
Temperature response soil respiration concentration readily decomposable C
2010/1/15
Temperature acclimation of soil organic matter (SOM) decomposition is one of the major uncertainties in predicting soil CO2 efflux associated with the increase in global mean temperature. A reasonable...
Effects of climate,fire and vegetation development on Holocene changes in total organic carbon concentration in three boreal forest lakes in northern Sweden
climate fire vegetation development Holocene changes organic carbon concentration
2010/1/14
Near infrared spectroscopy (NIRS), diatoms, pollen, charcoal, loss-on-ignition (LOI), and nutrient elements in lake sediments were used to assess important factors controlling Holocene changes in the ...
CO32− concentration and pCO2 thresholds for calcification and dissolution on the Molokai reef flat,Hawaii
CO32− concentration pCO2 thresholds calcification dissolution
2010/1/13
The severity of the impact of elevated atmospheric pCO2 to coral reef ecosystems depends, in part, on how seawater pCO2 affects the balance between calcification and dissolution of carbonate sediments...
