Asymmetry in CO2 emissions and removals could skew climate targets
carbon dioxide emissions climate targets carbon dioxide removals
2021/8/4
Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth's atmosphere are not equal to the climate changes from deliberate CO2 removals -- and assuming such a balance could lead...
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...

Many inverse problems in the atmospheric sciences involve parameters with known physical constraintsExamples include nonnegativity (e.g., emissions of some urban air pollutants) or upward limits impli...
Uncertainties in estimating regional methane emissions from rice paddies due to data scarcity in the modeling approach
estimating regional methane emissions rice paddies
2014/12/18
Rice paddies are a major anthropogenic source
