Belgian air quality observed from space


The goal of the LEGO-BEL-AQ project is to use the full spatio-temporal capability of the LEO and GEO Copernicus Atmospheric Sentinel missions in support of air quality policy in Belgium. LEGO-BEL-AQ stands for Low-Earth and Geostationary Observations of the Belgian Air Quality. The project includes the production of high spatial resolution maps of NO2 based on S5p-TROPOMI data for Belgium, and R&D on the complementarity and synergies within the (future) LEO+GEO constellation.
