To answer the question: What options are there to get better spatial and temporal resolution from space and ground?

For this project, we propose to build a mountaintop cubesat demonstrator overlooking the city of Innsbruck. We claim that in combination with local in-situ and remote sensing measurements and the modelling component, this entire system would meet all the objectives of the project.

The system will serve several purposes:

• Demonstrate the capabilities and test the performance of a cubesat prototype

• Monitor the AQ in and around Innsbruck at high temporal and spatial resolution

• Investigate the question of what is the best possible effective ground resolution that can be obtained with nadir looking remote sensing observations

• Assess the options for a high resolution AQ retrieval system combining measurements and model calculation
