Currently deployed (GEMS, TEMPO) and soon-to-be launched (S4-UVN) sensors constitute the first GEO satellite constellation for Air Quality observations in the northern hemisphere. The simultaneous availability of similar observations from platforms at LEO and L1 orbital configurations offers a unique opportunity for the integration of a quasi-global Air Quality observing system. In this presentation, we will discuss specific aerosol events to show the complementary nature of GEO aerosol observations and those of LEO (S5P-TROPOMI and S5-UVNS), and Langrange1-EPIC measurements. Integrated GEO, LEO and L1 observations will be used to demonstrate inter-instrument synergy for sensor calibration transfer, and the understanding of the nature of local events in regional and global contexts.
