Process-based models have been widely used to simulate the CH4 budget in natural wetlands,but there are still large uncenainties in ihe simulation processes.Accuracy analysis of process-based models is important to ev...

We re-evaluate the Raman spectroscopic quantification of the molar ratio and pressure for CH4–CO2 mixtures.Firstly,the Raman quantification factors of CH4 and CO2 increase with rising pressure at room temperature,ind...
