Short summary

Estimating emissions of greenhouse gases such as methane for individual countries is fundamental for climate mitigation policies. Numerical models can simulate how such emissions are transported to observation sites. Based on the observations, one can estimate the emissions. We describe how operational numerical weather prediction can help determine the model uncertainties and thereby improve the emission estimates. We test our system using simulated observations.
