* Time for low approaches at various airports refer to the time when the aircraft was at the lowest altitude above the runway; in general the whole pattern takes about 10‐15 minutes.

Funding:

This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 640458 (A‐LIFE). In addition, the German Aerospace Center (DLR) provided funding for a significant amount of flight hours and aircraft allocation days for the A-LIFE aircraft field experiment. Furthermore, two EUFAR projects were clustered with A‐LIFE and provided funding for 16 flight hours. Moreover, various groups participated in the A‐LIFE field experiment on their own funding.

Partners:

A‐LIFE involves partners from several European countries and the U.S. including the University of Vienna (UNIVIE, Austria), the German Aerospace Center (DLR, Germany), Institute for Tropospheric Research (TROPOS, Germany), Ludwig‐ Maximilians‐Universität (LMU, Germany), University of Natural Resources and Life Sciences (Boku, Vienna, Austria), Technical University of Darmstadt (Germany), University of Valladolid (Spain), EnviTech (Budapest, Hungary), National Oceanic and Atmospheric Administration (NOAA, USA), Karlsruhe Institute of Technology (KIT, Germany), TU Vienna (TU Wien, Austria), Austrian Weather Service (ZAMG, Austria), National Observatory of Athens (NOA, Greece), University of Crete (Greece), Cyprus University of Technology (Cyprus), University of Hertfordshire (UK), The Cyprus Institute (Cyprus), Institute of Physics Belgrade (Serbia).

We would like to thank EDT Hangar Services for hosting us during the A‐LIFE field phase in Paphos (Cyprus).
