DECSO-NRT-Europe aims to develop a near-real time (NRT) NOx emission service for Europe based on Sentinel data. NRT means emissions estimates are derived less than one month after the actual emission. In the first phase, we plan to build the NRT service for Sentinel-5P data, using the existing state-of-the-art inversion algorithm DECSO. In the second phase we intend to prepare a new emission service based on the Sentinel-4 and CO2M missions which will be launched in the near future. Sentinel-4 has the advantage of hourly observations of Europe, which is expected to improve the weekly/monthly emission estimates (less cloudy pixels), but also allow us to derive the diurnal cycle of the NOx emissions.
