2. Research aims of the regional AQ team at TNO
To combine earth observation data and modelling to obtain an optimal assessment of the air quality over Europe.
To quantify anthropogenic emission strengths by using EO data.
To quantify win-win strategies for mitigation of climate change and air pollution
