Report on OSSE on IRS NH3, O3/CO and Sentinel-4 NO2 capabilities and assimilation. D3.3
report
This report describes the activities conducted in the Task 3.3 entitled “OSSEs on IRS and Sentinel-4” performed during the CAMEO project. Section 3, which covers Subtask 3.3.1, presents the assimilation of synthetic ammonia (NH3) observations from the upcoming Meteosat Third Generation – InfraRed Sounder (MTG-IRS) satellite instrument into the LOTOS-EUROS and EMEP regional air quality models. Using advanced data assimilation techniques, an Observing System Simulation Experiment (OSSE) was performed that demonstrates that integrating high-resolution geostationary NH3
measurements can significantly improve the accuracy of simulated emissions, concentrations, and deposition fields across Europe. The work also identifies areas for further improvement in the data assimilation systems, such as optimizing vertical profile representation and temporal variability. The results show substantial reductions in model biases and highlight the potential of MTG-IRS data to enhance reactive nitrogen fields in air quality analyses and forecasts.
