Integrated Greenhouse Gas Monitoring System

The Integrated Greenhouse Gas Monitoring System for Germany (ITMS) is a BMFTR-funded project for validating and improving the estimates of greenhouse gas emissions in Germany. I work on the task of greenhouse gas flux inversion. Given observations of the greenhouse gas concentration, an atmospheric transport model, and an initial emission estimates, the inversion system improves the emission estimate using the information contained in the observations.
